the name came from Nihon which is one of the two ways to say “Japan” in Japanese, and literally mean “the Land of Rising Sun” Moscovium with the symbol Mc for element 115 and tennessine with the symbol Ts for element 117 were proposed by the discoverers at the Joint Institute for Nuclear Research, Dubna (Russia), Oak Ridge National Laboratory (USA), Vanderbilt University (USA) and Lawrence Livermore National Laboratory (USA) Both are in line with tradition honoring a place or geographical region Moscovium is in recognition of the Moscow region and honors the ancient Russian land that is the home of the Joint Institute for Nuclear Research, where the discovery experiments were conducted using the Dubna Gas-Filled Recoil Separator in combination with the heavy ion accelerator capabilities of the Flerov Laboratory of Nuclear Reactions Tennessine is in recognition of the contribution of the Tennessee region of the United States, including Oak Ridge National Laboratory, Vanderbilt University, and the University of Tennessee at Knoxville, to superheavy element research Lastly, and in line with the tradition of honoring a scientist, the name oganesson and symbol Og for element 118 was proposed by the collaborating teams of discoverers at the Joint Institute for Nuclear Research, Dubna (Russia) and Lawrence Livermore National Laboratory (USA) and recognizes Professor Yuri Oganessian (born 1933) for his pioneering contributions to transactinoid elements research His many achievements include the discovery of superheavy elements and significant advances in the nuclear physics of superheavy nuclei including experimental evidence for the “island of stability” Comments from the general public, during the month period were many Apart from many full agreements, comments were received suggesting other names, in some cases accompanied by petitions from large groups of people However, these suggestions could not be accepted, given the fact that under the current guidelines only the discoverers have the right to propose names and symbols Questions were also received about pronunciation of the names and the translations into other languages Members of the chemistry community also raised the concern that Ts is one of the two commonly used abbreviations for the tosyl group Recognizing however that many two-letter abbreviations have multiple meanings —even in chemistry, and for example Ac and Pr— the conclusion was made that the context in which the symbols are used, makes the meaning unambiguous “Overall, it was a real pleasure to realize that so many people are interested in the naming of the new elements, including high-school students, making essays about possible names and telling how ...New Headway Intermediate Testsorkbook with furtheronsolidation exercisesand writing tasks, atraditional methods oflanguage teaching andmore recentcommunicativeapproaches.

The worldwide volume of cement sales was higher than in the very strong first quarter of 2001, partly due to the extended scope of consolidation, while consolidated net sales were unchanged at CHF 2.8 billion despite currency losses. With the exception of North America, all Holcim Group regions made a considerable contribution to an encouraging consolidated result in overall terms. Consolidated operating profit fell slightly from CHF 324 million in the previous year to CHF 310 million. The 4 percent decline primarily reflects an absence of volumes due to the pro- duction outage at the Holcim US Portland plant as well as the crisis in Argentina. Excluding these factors, operating profit was significantly above the level for the first quarter of 2001. Consolidated net income reached CHF 77 million (first quarter 2001: 82), while cash flow from operating activities grew from CHF 74 million to CHF 108 million. The biggest gains of all were in Asia, Eastern Europe and once again Latin America. Rising demand for cement in Europe After a very cold January in many parts of Europe, demand for cement picked up rapidly in February and March and sales developed positively in a majority of cases. Significantly higher delivery volumes were achieved by Holcim Group companies in Central and Eastern Europe, but cement deliveries were also higher in Western Europe. At the same time, there was a slight weakening in the aggregates and concrete business, particularly in Western Europe. Consolidated operating profit for Group region Europe rose by 24 percent to CHF 63 million (first quarter 2001: 51). US Portland plant poised to come on stream The essential reinforcing work on the preheater tower at the new Portland plant has been carried out on schedule and production is to be geared up by the middle of the year. This means the US Group company will soon be able to make full use of its nominal capacity once again, thus impacting positively on the earnings situation from the second half of 2002. At Holcim US, a decline in sales of around 0.3 million tonnes, mainly due to the production outage at the Portland plant, rising distribution costs and increased write-offs in connection with the closure of the Fort Collins plant hit earnings in Group region North America in the first quarter of 2002, leading to an operating deficit of CHF 48 million (first quarter 2001: -9). The Canadian Group company St. Lawrence Cement achieved higher sales in all areas as well as improved financial results, although it could not fully compensate the setback at Holcim US. 2 Further improvement in results for Latin America Aside from Argentina, Latin America proved to be very stable in economic terms. Nearly all Group companies achieved a significant increase in deliveries. In particular, Apasco in Mexico made a substantial contribution to the strong performance. In contrast, construction activity came to a virtual standstill in Argentina, with Minetti suffering a 40 percent drop in cement deliveries. The 5 percent improvement in consolidated operating profit to CHF 209 million (first quarter 2001: 199) is due to the healthy profitability of the other Group companies in Latin America. Africa and Middle East maintain their position Cement consumption developed positively in this Group region. Exceptions included the West Africa group of countries as well as Madagascar and La Réunion. Holcim achieved a notable increase in sales across Lebanon, Morocco and Egypt. In overall terms, consolidated operating profit increased by 10 percent to CHF 55 million (first quarter 2001: 50), Eiríksson et al.

Research The distribution of four trace elements (Fe, Mn, Cu, Zn) in forage and the relation to scrapie in Iceland Tryggvi Eiríksson 1 , Hólmgeir Björnsson 1 , Kristín Björg Gudmundsdóttir* 2 , Jakob Kristinsson 3 and Torkell Jóhannesson* 3 Abstract Background: Previous studies indicated that the iron (Fe)/manganese (Mn) ratio in forage of sheep was significantly higher on scrapie-afflicted farms than on farms in other scrapie categories. This study was conducted to examine whether Fe and Mn in forage of sheep varied in general according to the scrapie status of different areas in the country. Copper (Cu) and zinc (Zn) were also included because of a possible relation to scrapie. Methods: The country was subdivided into seven Areas (I-VII). Three Areas (I, IV, VII) were designated scrapie-free (never diagnosed or eradicated) and three as scrapie-endemic (II, III, VI); status of Area V was taken as unsettled. Of the harvest 2007 1552 samples were analysed from 344 farms all over the country, mostly grass silage from plastic bales (>90%) and from the first cut (70% or more). Results were expressed as mg kg -1 dry matter. Results: Fe varied enormously from less than 100 mg kg -1 to 5000 mg kg -1 . Mn varied nearly thirtyfold (17-470 mg kg -1 ). Fe concentration was significantly lower in Area I than in Areas II, V and VI. Mn concentration was significantly higher in Areas I, IV and VII than in Areas II, III, V and VI. The Fe/Mn ratio was significantly less in Area I than in the other areas (except Area IV). Mean Cu concentration was 6.6-8.3 mg kg -1 and the mean Zn concentration was 24-29 mg kg -1 . They differed significantly in some areas. Conclusions: 1) Fe tended to be in lower amounts in sheep forage in scrapie-free than in endemic areas; 2) Mn was in higher amounts in forage in scrapie-free than endemic areas; 3) the Fe/Mn ratio was lower in scrapie-free than in endemic areas; 4) the Fe/Mn ratio may possibly be used as an indicator of scrapie status; 5) Cu and Zn in sheep forage were not related to scrapie; 6) further study on the role of Fe and Mn in the occurrence of scrapie in Iceland is needed. Background Jóhannesson et al. [1] have previously found significantly higher concentration of manganese (Mn) in the forage from scrapie-free farms in scrapie free counties (Category 1) than on scrapie-free farms (Category 2), scrapie-prone farms (Category 3) or on scrapie-afflicted farms (Cate- gory 4) in scrapie-affected counties in Iceland. Mn was also in significantly higher concentration in samples from farms in Category 2 than in Category 4 but not in samples from farms in Category 3. Although the Mn concentra- tions were found to vary highly in the samples they were in general in the same range as is considered as normal for plants [2]. The idea was subsequently promulgated that high levels of Mn in the forage of sheep, albeit in the normal range, might have a protective effect against the occurrence of clinical scrapie and the effect could possi- bly be confined to the cellular border of the gastrointesti- nal tract [1,3]. Later Gudmundsdóttir et al. [4] demonstrated the existence of a certain reciprocality between the iron (Fe) and Mn concentrations in the for- age of sheep. These authors found the Fe/Mn ratio signif- icantly higher in forage samples from farms in Category 4 than in the other categories. Thus the results would indi- cate that high amounts of Fe in the forage might some- how premise the occurrence of clinical scrapie.

[Start of press release] Website launches new resource for English teachers worldwide Derby, United Kingdom May 7, 2007 -Popular English teaching site www.englishbanana.com launches its new ‘English Banana.com Schools’ project in May 2007, which is aimed at making life easier for English teachers around the world The website, based in Derby, UK, currently gets 1.3 million page views per month from users in over 140 different countries It was founded in 2002 by English language lecturer Matt Purland Matt says: “Our site already offers more than 750 free photocopiable worksheets for learning English that teachers can print off and use It’s all free to access, and they don’t need to register We decided this year to provide a range of blank forms and templates that teachers can also print and adapt, enabling them to build their own English courses from scratch, without having to spend a lot of time and money either buying in or developing their own materials.” The new materials include staple forms that every English teacher has to either find or make themselves in the course of their daily teaching life, such as: ILPs (individual learning plans), blank lesson plans, initial assessments and schemes of work at different levels By using the materials provided for free on English Banana.com, teachers can spend less time making their own templates – by doing so reinventing the wheel – and more time working with their students The materials are provided as both pdf and Word doc files, so that they can be easily adapted There is also a support forum where teachers can ask questions, make suggestions and swap ideas Matt says: “This project is a result of feedback we’ve been getting recently from visitors to the site It became very clear that there was huge interest in gaining access to free materials that would support local schools around the world, including courses being run in teachers’ homes and in other informal settings One of the emails that inspired us was from a teacher named Evelyn Peralta, from the Dominican Republic She wrote: “‘I’m teaching English for free to a group of teenagers that are my kids’ friends As they cannot pay for it, and I want to teach my kids, I decided to create an ‘English Club’ for ten of them I prepare the lessons myself but it's hard for me, because I have to it at night and in my lunch time As I have a full-time job I use the internet in my lunch time to find things that can help me with the lessons Please let me know if I can count on you.’” As the website continues to receive requests for help from teachers like Evelyn all around the world, Matt hopes that the ‘English Banana.com Schools’ project, along with all the other resources that are freely available on the English Banana.com website, will go some way towards supporting educators like her, who are going out of their way to improve the lives of their students [End of press release] English Banana Schools ... realize that so many people are interested in the naming of the new elements, including high-school students, making essays about possible names and telling how proud they were to have been able to...
