This technology creates an accurate image (screenshot tools and the vertical seismic) on structural characteristics, layering, fractures, faults, texture and secondary porosity play an important desirable role in describing the reservoir. In the carbonate reservoirsthat most of Iran reservoirs are included in this type fractures are the most important factor in the production of these reservoirs. In the fractured carbonated reservoirs faults and folds makes unwanted changes in the structure of these reservoir. Structural complexities occur at different scales. For example, major faults and the original boundaries between formations are visible on the surface seismic data. But small-scale changes and faults in seismic data cannot be determined and it is essential to use small-scale of data and information sources. For achieving to these purposes it can be combined the result of small-scale data such as internal wellbore seismic VSP (vertical seismic profile) that having separating power in meter limit and FMI (formation micro imager) imaging logs that having separating limit in centimeter limit that could be able to modeling structural complexities and distribution of fractures around well. It should be noted that identifying occurrences around the wellbore is very important in drilling, completion procedures and development programs. FMI (formation micro imager) logs can be directly determined the inverted changes of wellbore layers and formation structures and also was an important factor for stratifying layers and determining the lithology of oil and gas explorations that can be determined the wellbore fractures, inclination and direction by using its interpretation. Moreover VSP (vertical seismic profile) logs is the way that generated signals at the surface are received by the geophone at different depth levels in the wells, which by its interpretation; changes in wellbore direction, velocity profiles, faults with higher accuracy around the wells and fractures around the well can be determined.","PeriodicalId":331621,"journal":{"name":"Journal of Marine Science: Research & Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116856689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Six sampling sites were selected on the basis of affected and unaffected areas of coal mining activities. Certain water quality attributes such as water colour, temperature, pH, dissolved oxygen, free CO2, chloride, total alkalinity, total dissolved solids, nitrate, ammonia, phosphate and sulphate were analysed along with the assessment of relative abundance of fishes. The estimated value of studied water quality parameters such as pH, dissolved oxygen and total alkalinity indicates degradation of water quality due to the effect of acid mine drainage (AMD) of coal mining. Polycyclic aromatic hydrocarbon (PAH) showed highest concentration of 4-ring PAH and Benzo[a]anthracene was the most important pollutant in the water collected from affected sites. Relative abundance of fish diversity was also estimated less in affected area of the River. A total of 64 fish species under 20 families were collected with highest number in cyprinidae family. The calculated value of diversity indices reflected the declining trend of fish diversity in the coal mining affected areas of the river due to degradation of water quality.","PeriodicalId":331621,"journal":{"name":"Journal of Marine Science: Research & Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125761502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 1982 experiments in television photography instrumented by the Soviet VENERA-13 and VENERA-14 landers, returned panoramas of the Venus surface at the landing site. Over the past 33 years, no similar missions have been sent to Venus by any space agency, mainly due to the reason that the experiments were of extreme technical complexity. Analysis of treated once again VENERA panoramic images revealed objects that might indicate the presence of hypothetical forms of Venusian flora and fauna. Among them is ‘amisada’ that stands out with an unusual shape against the stone plates surrounding it. The ‘amisada’ can be included into the list of the most interesting findings of the hypothetical Venusian fauna. Among hypothetical fauna entities of Venus, certain unusual findings that have similar structure were found in different areas of the planet. Their unusual shape was repeated on various panoramas that were taken by landers' cameras and have attracted attention. 'Stems' objects possess apparent terramorphic features of Earth-like floras. 'Stems' are thin vertical trunks that have a thickness of 0.3-3 cm and are 0.1 to 0.5 m in height. On close objects, one can see that the 'stem' at the top end is provided with a large bulge, a \"burgeon\" or “flower” that is 2-8 cm in diameter, with “petals” surrounding a bright center. At the base of the 'stems', there are features that resemble leaves in a quatrefoil. Probably, 'stems' are widespread on the planet, because found at the different sites. The terramorphic features of the hypothetical fauna and flora of Venus, if they are confirmed, may point out at outstandingly important general laws of the animated nature. Some data on physical settings on Venus are applied together with a hypothesis on photosynthesis used by Venusian flora.","PeriodicalId":331621,"journal":{"name":"Journal of Marine Science: Research & Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134465799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aurelia aurita complex life cycle consists of several stages including alternating generations of sexual adult stage medusa and asexual stage polyp (scyphistoma). The main difference between polyp and medusa is the degree of the ECM (mesoglea) development. The new protein “mesoglein” was determined as one of the main components of mesoglea. Mesoglein is the component of the mesoglea “elastic” fibers. Previously we found that according to reverse transcription PCR mesoglein is expressed in the mature medusa exclusively in the mesogleal cells. The aim of the current work was to find out at what stage of development the specific mesoglein expression occurs. Mesogleins’ expression have been checked by PCR with specific primers on the template of transcriptomes’ cDNA from different stages; by mesogleins’ antibody staining on SDSPAGE and on paraffin sections; by histochemistry staining. In A.aurita life cycle mesoglein synthesis begins at scyphystoma polyp stage at RNA and protein level in mesogleal cells (Mc) which separated at this stage as the cell type. Mesoglein stored in granules both in Mc of adult medusa and polyp on its’ way to ECM elastic fibers. Our data perfectly correspond to the recently reported de novo transcriptome assembled from Illumina RNA-Seq data generated from six stages throughout the Aurelia life cycle.","PeriodicalId":331621,"journal":{"name":"Journal of Marine Science: Research & Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134080291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In 1816, Jean Lamarck (1744-1829) introduced the purple sea urchin (Paracentrotus lividus) as a new species, and six decades later, Oscar Hertwig (1849-1922) used this model organism to elucidate external fertilization at the sub-cellular level. Moreover, Hertwig referred to “gender” to denote male or female P. lividus-individuals (gonochorists). Sexual reproduction and gender-roles are also outlined with reference to the fish leech (Piscicola geometra), a protandrous hermaphrodite characterized by hypodermic insemination and a gender-ration of 50:50.

CO2 assimilation reaction is the reaction of CO2 with water to produce carbohydrate absorbing heat. Burning reaction is reverse reaction of CO2 assimilation. If we can compensate the generation of CO2 and heart of burning with the absorption of CO2 and heart by CO2 assimilation, global warming can be protected. Plankton CO2 assimilation reduced 95% CO2 in Precambrian Eon to 400 ppm now in 35 billion years. It is said that 70% CO2 assimilation is carried out at sea. Supply of nutrient N and P to sea is most important. Large amount of NOx is produced when fossil fuel is burned. This NOx should be released without elimination procedure as it is. Large amount of N and P is contained in drainage. The drainage should be released as it is. Deep sea water contain much nutrient N and P. Shallow sea water contain very little nutrient. Agitation of deep sea water with shallow sea water increases the plankton growth. These three points are effective methods to increase the plankton growth, to increase fish production and reduce CO2 production and to protect earth warming.","PeriodicalId":331621,"journal":{"name":"Journal of Marine Science: Research & Development","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116029588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
