Abstract: The alignment of gas pipelines in a rugged terrain has always been a serious challenge around the globe but they can be perfectly aligned with the help of Geo-Spatial technologies. When South Zarghun gas fields were discovered in Pakistan, gas transmission pipeline laying process between gas fields and Quetta city was as challenging task for the Government of Pakistan. Very rough terrain and extreme weather conditions especially in winter season were the two major constraints for the alignment of pipeline. Geomatics survey was essential before transmission pipeline construction work, done twice by private consultant in Pakistan’s local geographic coordinate system. SSGC took decision in 2006 for the construction of pipeline but unfortunately it could not be executed due to law & order situation in Pakistan especially in Balochistan province and later all bench marks of pipeline alignment route were vanished by the locals. In 2012, SSGC again started pipeline construction work on war steps. Previous pipeline alignment survey was converted into existing SSGC’s GIS coordinate system i.e. UTM Zone 42 WGS84 using ESRI ArcGIS software. Identification & re-installation of all bench marks and re-routing of pipeline were done by SSGC GIS survey team with the help of global positioning system (GPS) and satellite data. Finally, right of way (ROW) of transmission pipeline from Zarghun gas fields to Quetta city was designed and produced in the form of GIS map for pipeline construction activities.

Abstract: Centenarian research contributes to expanding our knowledge on longevity and healthy aging. In Greece, a variety of studies have been conducted in order to explore exceptional longevity. This is a retrospective study of 106 centenarians employing both quantitative and qualitative measures in order to explore centenarians own perspective on longevity. Basic socio demographic and life style variables where associated with centenarians beliefs and perceptions about their longevity. The majority of centenarians attributed their longevity to God and to living a good life overall. God and social networks were reported as their main source of strength in order to continue living. Gender differences were also evident as male centenarians reported non abusive behaviors and a sense of having a measure in daily living, as well as nutrition as their main source of longevity, while female emphasized on God and social networks. Gender differences on Body Mass Index and Smoking are also evident. Centenarians own perception of longevity could be further explored and findings could be incorporated in future research and intervention programs aiming at healthy longevity. Keywords: Centenarians, longevity, Greek Population, aging. Download Full Article |

Abstract: Since morphological markers are recognized as useful tools to evaluate events of anthropic disturbances, we performed a preliminary study on head shape variability in the riverine-dwelling Leuctra fusca larvae as early alarm systems in running waters. Particularly, heads of 32 larvae were collected from two localities of River Aniene (central Italy) and photographed for digitizing landmarks and semilandmarks. The Cartesian x-y coordinates of all points were firstly converted to shape coordinates by Procrustes superimposition, and then analyzed for exploring the full potential of the application of geometric morphometric techniques. Where the principal component analysis revealed a clear pattern of variation between the 2 sampling sites, the Procrustes ANOVA highlighted this variation as highly associated with fluctuating asymmetry, the latter being traditionally connected with developmental accidents due to environmental conditions. No directional asymmetry was observed. Finally we didn’t find any pattern of allometric variation in the studied structure. Our study indicates that further studies ought to be employed to use geometric morphometrics as a valid tool for detecting and describing morphological variation as biomarkers in invertebrate organism such as stoneflies. Keywords: Asymmetry, biomarker, central Italy, freshwater, geometric morphometrics.Download Full Article |

Abstract: The production of grapevine is important agricultural sector in Turkey. But, the production is lower than the other Mediterranean countries. One of the main reasons of low yield is many viruses’ diseases. The nepoviruse diseases are responsible for significant lossesin vineyards. Grapevine fanleaf virus (GFLV) is the most important deadly virus among them. It is transmitted by graft and vector nematodes. It has not been studied enough about this virus in our country. There is not enough detailed research on this virus in our country. In this study, the maintenance of GFLV in vineyards and their occurrence areas were determined in Adana and Mersin provinces by serological and biological assays. Out of total 384 grapevine samples, 63 plants (16.4%) were found to be infected with GFLV by double-antibody sandwich enzyme-linked immunosorbent assay (DAS-ELISA). In addition to this, as herbaceous indicator plants; Nicotiana benthamiana Domin., N. tabacum L., N. rustia L., Chenopodium amaranthicolor Coste et Reyn., C. quinoa Wild., Cucumis sativus L., and Gomprena globosa L. were used in biological assays. But chloroticlocallesions were observed only on Nicotiana benthamiana Domin. among weedy indicator plants by mechanical transmission.
