From the time when it was first launched in 2005, satellite data generated from Google Earth are freely available online. Hence, without being conducting concrete studies about the accuracy of satellite data from Google Earth, Google Earth are chiefly used for different field of studies in different sectors for different purposes in Ethiopia. In this regard, it was planned to conduct this study by establishing the main objective to evaluate the positional accuracy of Google Earth. Hence, in order to address the aforementioned objective, a brief methodology for collecting and analyzing data was performed. The positional accuracy of Google Earth for both horizontal and vertical cases was evaluated. The acquired horizontal RMSE of Google Earth was found fit to produce a class-1 map of having 1:20,000 scale as recommended by ASPRS-1990. Unlike for horizontal case, the computed RMSE for vertical positional accuracy of Google Earth was not found fit for preparing class-1 map. However, making correlations between field survey and GE can provide 95% fitness, and also, subtracting the acquired RMSE for the vertical case from the original Google Earth elevation data can provide a 90% fitness for preparing class-1 map as well.

Prevention of global warming is becoming urgent issue and "biofuel" gathering worldwide attention has been put into practical use not only in US, EU, Brazil or other countries but in Japan. As for its impact on environment, however, evaluation still varies including aninfluence on global economy, for example food price crisis that might have been caused by competition with food. In the previous study [1], one of the authors pointed out that "bio-ethanol" from crops is never "carbon neutra", that means the production and use of the fuel does not lead to a net increase in atmospheric CO concentration, nor useful as a countermeasure against global warming. The "second-generatio" of bio-fuel made from nonfood biomass has attracted much attention especially after the Hokkaido Toyako G8 summit held in November 2008. Among various plants or biomass materials, "Jatropha" has come to the front as one of the most promising candidates for future bio-diesel production. In fact, there are many plans or projects aiming at large scale cultivating Jatropha for bio-diesel oil production in several African or Southeast-Asian countries. However, it should be pointed out that there are too many unknown factors still remaining that are important in practical use of Jatropha oil, for example, productivity as well as sustainability, long-term impact of its large-scale use on soil quality, practical costs of the oil and so on. In this study, an assessment on the validity of Jatropha production was tried as quantitatively as possible using the data obtained from a field survey in Indonesia conducted by the authors in January and March of 2009. Although LCI data for LCA calculations obtained was very limited, the true reality of the situation about Jatropha could substantially be demonstrated to some extent. The main point was that the oil cost was dominated mainly by labor costs, because many work operations could not be mechanized and inevitably be manual handling tasks. In many cases, the labor costs could not be covered by the income from the Jatropha oil (or seed) due to the low productivity of the biomass, whereas the prime cost of the biodiesel oil was rather high expensive compared with fossil fuel.

Large scaled projects are conducted in South Yellow Sea in recent years. Topographic effect and tidal current are key issues to the coastal engineering and the ocean engineering. In this study, field surveys were conducted to investigate the tidal level, current velocity, and current direction in South Yellow Sea. A numerical model was developed to simulate the radial current field based on the field data. To investigate the mechanism of the radial current field, the actual topography and a smoothed topography were applied in the numerical model, respectively. Results show that, the current field appeares radial because of the tidal system rather than the submarine topography. Local topography centralized the radiation centre and shifted the high-velocity zones. The actual topographic effect is proposed, and results show that local topography increases the flood tide velocity and decreases the ebb tide velocity. Lagrangian residual currents are calculated to illustrate possible sediment sources and transport routes.

The main goal of the present paper was to study the physical response of a double side skin (DSS) structure under impact load in a collision event between two ships. Collision energy and damage extent (size and location) during the collision process were observed together with damage patterns on side structure. The ships were modeled after a Ro-Ro passenger ship and cargo reefer which were involved in a ship collision on the Sunda Strait while the analyseswere performed using non-linear simulations FEMto produce virtual simulation data. Several caseswere proposed to be investigated in this work with involvement of parameters i.e. penetration location and ship materials which were embedded on the structure model. A series of material experiments and testing was conducted to obtain detailed material properties which were to be deployed in simulation. It was shown that, after penetration at the transition location, the striking ship was successfully deforming and forming tears to the inner skin. On the other hand, with identical structure and identical mass of construction, the use of high-strength low-alloy (HSLA) steel as the repair material offered considerably better capacity in absorbing the impact load than plain-carbon steel.

This preliminary report summarizes the results of the archaeological research in the oases in the Kugitang Piedmont after the second season (summer 2016). The field survey in the Zarabag Oasis, which was the subject of our interest in the first season, was accomplished and the research continued in the oases where the villages of Karabag and Kampyrtepa are situated. The prospection led to the detection of new archaeological sites in both of them. Moreover, the examination of the sites previously known from earlier works was conducted. Besides this we focused on the the mapping of the water sources. The collected data have been processed in GIS and the finds were analysed and dated. Preliminarily, we observe basically a similar dynamic in the settlement patterns of all the researched oases.

Cephus fumipennis Eversmann is a key insect pest of wheat crops in Qinghai, China. Its field population densities were surveyed by using both the back-loaded insect vacuum and a sweep net. Mean densities in township-level were calculated and a quantitative relation, ỹ =0,664 + 0,214 x, was established between the two sampling methods. The empirical relationship may be applicable in density monitoring and Integrated Pest Management program of the insect.

The paper proposes a work flow before, during and after the archaeological field survey, with the use of mobile GIS technology, aimed at verifying the location of archaeological sites, documented in the 1980s and 1990s. The first part characterized the field survey and of scientific and conservation assumptions of the program called the Polish Archeological Record, which became the basis for a national register of archaeological sites and the current source of spatial data acquisition. The text specified also circumstances needed to carry out verification research. Further part described the steps of the research process, carried out with the use of traditional methods and based on the analog records. Additionally, areas endangered by the risk of generating errors were highlighted. The next part proposes workflow on the mobile devices with GIS, with a focus on the process of preparing materials for actions in the field - acquiring digital data from analogue maps. The text compares the possibilities and characteristics of GPS navigators, tablets and smartphones with Google applications and PDAs with GIS software as research tools for the verification of data obtained. Key features of selected devices and applications are summarized in the table. The summary indicates the benefits of the new solutions during the field survey, significant changes in relation to traditional methods, and the postulate to take into account new technologies and adapt to them the collected information about the resources of the archaeological heritage in the national conservation offices.

Data (2083 sites visited) collected during the otter Lutra Intra (Linnaeus, 1758) survey of Poland in 1991-1994 were used to evaluate some of the factors affecting the efficiency of the technique. The success in detecting otter signs was found to be significantly affected by the presence of "spraintable" bridges and other potential sprainting sites on the banks. Decreased efficiency of the technique was noted in specific habitats, eg large rivers, canals surrounded by open fields or meadows, and any aquatic habitats with few potential sprainting sites on the banks. It is suggested that modifications: spot checks at additional bridges and extended searches of river banks, could be used to improve the reliability of the survey in areas with low numbers of otter signs.

Field surveys of rare and elusive reptiles often encounter the problem of low detectability. Therefore, several techniques have been invented to improve detection probability and artificial cover objects (ACOs) are among the most commonly used in reptile studies. However, the methodological effectiveness of ACOs has been rarely evaluated and focused mostly on spatial aspects. The temporal dimension of the ACOs effectiveness remains still understudied, despite well-known seasonal variation in reptile activity patterns. Here, we examined seasonal and between-year variation in the fraction of occupied ACOs, as a proxy for detectability, in two elusive reptile species, the slow worm Anguis fragilis and smooth snake Coronella austriaca. We found that the use of ACOs was species-specific and showed high temporal variation. In the case of smooth snakes, monthly usage varied between years; specifically within-year variation of the proportion in occupied ACOs was most pronounced in 2015, but seems vanishing in consecutive years. This loss of of seasonal pattern occurs only in the last year of survey in the case of slow worm and monthly use of ACOs seem not to vary between years. Considerably low detectability of the studied species by the ACO method in some years may not necessarily indicate their low population density, but rather results from shifts in their diurnal activity and/or microhabitat use dependent on ambient temperatures. Increasing between-year variation in weather conditions may reduce repeatability of seasonal patterns of ACO usage, making we suggest additional detection techniques that could bee incorporated.

Information on the spatial variability in plant disease is essential for location-based disease management. In the current study, the spatial distribution of tomato early blight disease was ascertained in District Gilgit, GilgitBaltistan, Pakistan. The comprehensive field survey was carried in two growing seasons (2014–2015), whereas in each growing season, 62 tomato fields were surveyed. Based on the distribution of disease, the respective thematic maps (incidence and severity) were prepared using Arc Map 10.1 with spatial analyst function of Arc GIS software by means of the inverse distance weight (IDW) interpolation method. Results indicate that early blight of tomato is spatially distributed in both growing seasons. However, in the first growing season, the disease incidence ranged from 10.22% to 44.16% and during later season 14.03–49.16%, whereas 5.37–16.40% and 6.52–26.94% severity was recorded. Furthermore, this information indicates that higher disease infestation occurred in 2015 in relation to 2014. This information linked to metrological data (temperature, precipitation and relative humidity), seemingly favored the early blight development during the growing period. Seven botanical extracts were tested against pathogen Alternaria solani at different concentrations (4, 6 and 8%). Results revealed that all tested plant extracts showed antifungal activities. However, at 8% concentration of plant extract, Datura starmonium, Berberis orthobotry, Podophyllum emodi and Uretica dioica exhibited >60%, while Peganum harmala, Artemisia maritima and Capparis spinosa <60% antifungal properties. The information generated due to this study could help the tomato growers regarding disease management and selection of resistant cultivars, improving profitability and food security in the Gilgit region.
