The environmental causes of cancer distribution in Syria

In the last decade Syria witnessed a boost in cancer incidences, as well as high mortality ratios. This research aims to illustrate the geographical distribution of cancer over Syria in details and to trace the expansion of incidence through time according to risk factors like age, gender, human behaviour. The paper consists of four parts: 1- Introduction to the topic (cancer and the environmental influence of its distribution) and explanation of the used terms. 2- The relationship between cartogeographical sciences and the topic of the paper. 3- Building a Geographical Information System according to the major district in Syria. 4- Building a Geographical Information System for the southern part of Syria (the most infected place). 5- Results and discussion. The study employed the geographical tools to investigate the geographical distribution of cancer disease and the environmental factor that controls this distribution. The used methods are the statistical, systematic, analytical descriptive, comparative and the cartographical which were employed differently according to the data characteristics. Personal and spatial data were collected from treatment points in a questionnaire that allowed adjusting each of them on the electronic interactive map. Data was analysed statistically and cartographically depicted. Accordingly parallel descriptive and comparative data were added for reaching the final conclusions. Thematic maps were the final product of using GIS. The cartographical product helped to analyse the epidemiological cluster and the accumulated risk factors. The resulted maps were an analytical tool revealing the concepts of spatial data. Natural risk factors were the main focus in addition to people nutrition habits. The studied factors were depicted in three map scales. The recorded incidences for 2002 till 2008 were depicted as well. The output is an atlas of: 1- 1/2000,000 Syria maps showing the big clusters of the disease and the risk factor. 2- 1/2000,000 Choropleth maps showing the ratio of incidence to the census of each Syrian district, 3- 1/200,000 for the southern part of Syria which showed the highest incidence ratios (Al-Souida county). The study showed many clusters based on the kind of cancer and the kind of risk factor and drew the attention to some risk factors that people disregard (the frequent relative marriage in the region of Al-Souida) and some uncommon ones like rock type (Al-Souida). Tracing pollution in time line helped to link the earlier influences and the accumulated factor to the recent incidence. the geographical risk factors were the minor reasons for the cancer clusters (elevation height, solar radiation, rock type, polluted gases in the atmosphere and water wells), meanwhile people habitual activities were the major reason (kind of job, smoking and nutrition system). Considerably some urgent risk factor caused the small clusters up on different groups of people (eating food exported to the city of Dier al-zor which was polluted by radiation)

Users characteristic influence on the efficiency of typographic design

This paper investigates the efficiency of typographic design using Bertin’s variables, both individually and combined. A user study was con-ducted in which two types of map users had to perform a search task. The first group consists out of participants who have been trained in cartog-raphy and who use maps on a daily basis. The second group of users are novices who have not got any previous education in cartography. Users’ efficiency was calculated by measuring the consumed time to find the target label. The obtained data was analyzed statistically to compare the efficiency of users’ performance regarding the applicability of visual variables on la-bels. Using ANOVA showed some significant differences between users’ group and within users’ groups (P<0.05)

6-loop anomalous dimension of a single impurity operator from AdS/CFT and multiple zeta values

Anomalous dimension of the simplest nontrivial single impurity operator in the beta=1/2 deformed theory is determined at six loops from the AdS/CFT correspondence. L\"uscher correction is evaluated at next-to-next-to-leading order (NNLO) in terms of multiple zeta values. The result can be simplified into the products of simple zeta functions and the same form of the correction is expected for the Konishi operator at six loops, too.Comment: 14 pages, references added, numeric coefficient in (5) corrected, which changes the numerical result, but not its structur

Label size design : aesthetics and effeciency

Considering label as one of the important map component, this paper is an attempt to provide empirical evidence of label size design rules and frames which is based on the design aesthetics and efficiency. Determining the ‘best’ legible label size is critical concern involves testing design aspect and needs. Both aesthetics and efficiency can set the design frames for better perception and legibility. Aesthetics was calculated by determining users´ preference of different use of label sizes, whereas efficiency was calculated by measuring time to locate targets of different. Both areal and point data were involved in the study to determine the combination of the two measurements of label size design. Digital maps were designed and presented to users as they were firstly asked about their preference of different use of label size, and secondly they were asked to locate different label size. The intersection between the first test and the second one attributes the frames for label size design. The correlation between the preferable sizes and the efficient sizes is being traced and the relation between label size aesthetics and efficiency is being identified. This study indicates the need to test other visual variable in order to serve many labelling functions

Optical Properties of Bismuth Nanostructures Towards the Ultrathin Film Regime

Bulk bismuth presents outstanding optical properties, such as a giant infrared refractive index (n near 10) and a negative ultraviolet visible permittivity induced by giant interband electronic transitions. Although such properties are very appealing for applications in nanophotonics, the dielectric function of bismuth nanostructures has been scarcely studied. Here, we determine by spectroscopic ellipsometry the far infrared to ultraviolet dielectric function of pulsed laser deposited bismuth thin films with nominal thickness tBi varied from near 10 nm to several tens of nm. For tBi above 15 nm, the films display a continuous structure and their dielectric function is comparable with that of bulk bismuth. For tBi below 15 nm, the film structure is discontinuous, and the dielectric function differs markedly from that of bulk bismuth. It is proposed from FDTD simulations that this marked difference arises mainly from effective medium effects induced by the discontinuous film structure, where quantum electronic confinement does not play a dominant role. This suggests that ultrathin and continuous bismuth films should present the same outstanding optical properties as bulk bismuth for high performance nanophotonic devices
