This is an econometric analysis of demand for travel to Cyprus by Britons. We examined the competitive and complementary relations between travel to Cyprus and other well-established travel destinations in the Mediterranean basin. Because many package tours include several countries in their destinations within a given journey, and because individual travelers find it more advantageous to visit more than one country in a single trip, it may be meaningful to examine international travel within the contest of groups of countries rather than a single country competing for international travelers. Specifically, we provide an analysis of the competitive and complementary relations existing between the tourism sectors of Cyprus and that of Greece, Spain and Portugal for British travelers. We provide estimates of income and relative price elasticities based of export demand equations upon annual data from 1980-2016. We tested for the stationarity of the variables and derived estimates of the Vector Error Correction Model (VECM). These tests confirm a strong association between the incomes of Britons and their decision to travel to Cyprus. Furthermore, we show the relative prices between Cyprus and other competing destinations in the Mediterranean to play an important role in determining British travel to Cyprus.

Most recently, Uganda increased its trade engagements with COMESA as demonstrated by its submission of accession instruments to COMESA Secretariat in order to access the Free Trade Area (FTA). It is envisaged that trade with COMESA can compensate for the low export demand elsewhere by enabling diversification of the export basket and facilitating value addition to traditional exports. It is also expected to enhance producer competitiveness and consumer welfare. Full exploitation of this requires information on where and in what commodities Uganda’s trade niche lies. This study assesses the country competiveness within COMESA based on the concept of Revealed Comparative advantage (RCA). The paper also evaluates the stability of Uganda’s RCA in COMESA from 1997-2014 using HS6-digit level export and re-exports data obtained from the World Integrated Trade System. Findings reveal that Uganda’s RCA is in all 16 industries at the product chapter level. It is stable in exports of animals, vegetables, food production, wood, textiles, & cloth, stone & glass and metals. Policies for further development of these sectors should aim at addressing sectoral challenges including the low productivity, marketing, and processing capacity in the animal sector, low capacity to test phytosanitary and sanitary certification in the vegetable sector. Additionally, tackling market and low production challenges for the textile sector and, high costs of production for the metals sector will further boost exports to the region.

Conti: One of the main conclusions of the Wolf-Rayet symposium in Buenos Aires was that Wolf-Rayet stars are evolutionary products of massive objects. Some questions:–Do hot helium-rich stars, that are not Wolf-Rayet stars, exist?–What about the stability of helium rich stars of large mass? We know a helium rich star of ∼40 MO. Has the stability something to do with the wind?–Ring nebulae and bubbles : this seems to be a much more common phenomenon than we thought of some years age.–What is the origin of the subtypes? This is important to find a possible matching of scenarios to subtypes.

AbstractBy using the stability condition and general formulas developed by Fukushima (1998 = Paper I) we discovered that, just as in the case of the explicit symmetric multistep methods (Quinlan and Tremaine, 1990), when integrating orbital motions of celestial bodies, the implicit symmetric multistep methods used in the predictor-corrector manner lead to integration errors in position which grow linearly with the integration time if the stepsizes adopted are sufficiently small and if the number of corrections is sufficiently large, say two or three. We confirmed also that the symmetric methods (explicit or implicit) would produce the stepsize-dependent instabilities/resonances, which was discovered by A. Toomre in 1991 and confirmed by G.D. Quinlan for some high order explicit methods. Although the implicit methods require twice or more computational time for the same stepsize than the explicit symmetric ones do, they seem to be preferable since they reduce these undesirable features significantly.

The method demonstrated is an adaptation of a proven procedure for accurately determining the magnification of light photomicrographs. Because of the stability of modern electrical lenses, the method is shown to be directly applicable for providing precise reproducibility of magnification in various models of electron microscopes.A readily recognizable area of a carbon replica of a crossed-line diffraction grating is used as a standard. The same area of the standard was photographed in Phillips EM 200, Hitachi HU-11B2, and RCA EMU 3F electron microscopes at taps representative of the range of magnification of each. Negatives from one microscope were selected as guides and printed at convenient magnifications; then negatives from each of the other microscopes were projected to register with these prints. By deferring measurement to the print rather than comparing negatives, correspondence of magnification of the specimen in the three microscopes could be brought to within 2%.

The strengthening effect at high temperature produced by a dispersed oxide phase in a metal matrix is seemingly dependent on at least two major contributors: oxide particle size and spatial distribution, and stability of the worked microstructure. These two are strongly interrelated. The stability of the microstructure is produced by polygonization of the worked structure forming low angle cell boundaries which become anchored by the dispersed oxide particles. The effect of the particles on strength is therefore twofold, in that they stabilize the worked microstructure and also hinder dislocation motion during loading.

It is well known that the resolution of bio-molecules in a high resolution electron microscope depends not just on the physical resolving power of the instrument, but also on the stability of these molecules under the electron beam. Experimentally, the damage to the bio-molecules is commo ly monitored by the decrease in the intensity of the diffraction pattern, or more quantitatively by the decrease in the peaks of an energy loss spectrum. In the latter case the exposure, EC, to decrease the peak intensity from IO to I’O can be related to the molecular dissociation cross-section, σD, by EC = ℓn(IO /I’O) /ℓD. Qu ntitative data on damage cross-sections are just being reported, However, the microscopist needs to know the explicit dependence of damage on: (1) the molecular properties, (2) the density and characteristics of the molecular film and that of the support film, if any, (3) the temperature of the molecular film and (4) certain characteristics of the electron microscope used
