[en] Full text. The Ba Hf O₃ is a compound belonging to ABO₃ perovskite family whose structure is reported as cubic over the whole temperature range, similar do that of the Ba Ti O₃ paraelectric phase. Meanwhile, the X-ray diffraction spectroscopy (XRD) assign to this compound a cubic structure, pertubed angular correlation spectroscopy (PAC) shows a dynamic effect around the probes (Hf sites), measured from RT to 1100⁰C. This last means that the mean value of the principal component of the electric field gradient tensor at the probes ¹⁸¹Ta(Hf) is non vanishing and fluctuating with time. The aim of this work is to give some light about this problem. In that way, we measured this compound by far infrared spectroscopy (FIR) at 80 K. The spectra show that although the main cubic perovskite bands are well defined, appear in them weaker substructure that implies a lower effective space group. Our analysis of the data by KK and LST generalized model indicate that it is possible to explain these extra peaks with an orthorhombic distortion similar to that we already found for Sr Hf O₃.

[en] Data of 104 patients treated between 1970 and 1991 for prostate carcinoma by definitive radiation therapy in our institution were analyzed. The greater part are B and C stages carcinomas and mean age was 69.5 years: Trans urethral Resection was the most common procedure of histological sample obtaining (42%) followed by transrectal biopsy (27%). Treatment was performed in a Cobalt unit or Linear Accelerator using 18 Mev photon beam. The prostate mean dosage was 64.5 Gy. The 5 years free local recurrence survival was 100%, 72%, 71% and 37% for A₂, B; C y D₁ stage patients. Ten years free local recurrence survival was 72 and 71% respectively for B and C stages. Five years free disease survival was 100%, 57% and 49% respectively for A₂ b an C stages. Ten years free disease survival was 50 and 37% for B and C stage patients. A multivariate Analysis (Cox regression) was performed and the tumour response following the irradiation was obtained as the most important prognostic factor. (Author) 11 refs

[en] Objective: To evaluate the incidence of TPM in Uruguay through the RNC data. Materials and Methods: Of the incident cases registered in 2008, they were selected those presented in the database prior cancer registry. The are excluded in situ of the cervix and non-melanoma skin carcinomas. Results: At the present time are entered to the the base of the RNC 11859 new cases of cancer incidents in 2008. Of these 566 (4.7%) had a prior record of criteria selection where 308 were women and 258 men. Of these, 450 met the IACR / IARC criteria (*). (Two topographies and / or different histologies). The median age of first tumor presentation was 65 years (22-89). The second 71 years (27-94). The median of the difference was about 4 years Analyzed by gender: Breast cancer (CM) was the most frequent tumor in women, cancer as first (142) and as second (85). The most common associations (excluding Bilateral) CM, CM with gynecological tumors were (TG: ovarian and corpus uteri) 11% CM and colo-rectum (CCR) (9.4%), TG and CCR (5%). 26% of female cases occurred in two hormone-dependent tumors (CM and CM bilateral or TG). In men prostate cancer (PC) is the most common tumor as first cancer (76) but the CCR is the most frequent and second (56). The association comprises CP-CCR 15% of cases and CP association and transitional tumors (TT) 10%. The association of two or more snuff-dependent tumors was observed in 8% of cases. When discriminated by sex in men is 13%, amounting to 19% if taking into account the multiple TT, while in women corresponds to 2%. Conclusions: The profile presentation of TPM in the RNC of Uruguay is similar to that reported other records in both frequency (depending on the criteria that defined) and associated type of tumors. The most frequent associations also They are similar to those observed by other authors: CCR, CM and TG women and CCR, and CP TT in men. The association of tumors are also observed with risk common factors: in women hormonal factors linked to smoking and men. (*) International Association of Cancer Registries (IACR).

[en] Objective: To analyze the geographical distribution of mortality from lung cancer in Uruguay, using spatial autocorrelation indicators, in order to identify regions of high and low risk in the period 1989-2008. Methodology: 1989-2008 interval was analyzed by grouping the data in the following periods: 1989-1991,1992-1994,1995-1997,1998-2000,2001-2003 and 2004-2008. As indicator risk S MR (Standardized Mortality Ratio) was used, with reference to the country as a entirety. The analysis was performed by calculating the index I and correlation plots space (both methods according Mo ran) for each period and the corresponding maps. The significance was determined by permutations, considering level 0.05 significance. Results: The results of the correlation coefficients for different periods were, in Men: 1989 -1991 (R = 0.29, p <0.05), 1992 -1994 (I = 0.11, N S), 1995 -1997 (R = 0.31, p <0.05); 1998 - 2000 (R = 0.24, p <0.05); 2000 - 2003 (R = 0.19, p <0.05); 2004 -2008 (R = 0.24, N S). In women: 1989 -1991 (R = -0.18, N S), 1992 -1994 (R = -0.16, N S), 1995-1997 (I = 0.18, N S); 1998 - 2000 (R = 0.06, N S); 2001-2003 (R = -0.16, N S), 2004 -2008 (I = 0.02, N S), 1989-2003 (R = -0.03, N S). Men in those departments where they met more risks Artigas were low (SM R = 0.52; 0.57; 0.61; 0.61; 0.60; 0.69), Salto (SM R = 0.52; 0.57; 0.58; 0.68; 0.76; 0.75), Black River (SM R = 0.69; 0.73; 0.76; 0.93; 0.73; 1.29) and Paysandu (SMR = 0.87; 0.85; 0.96; 0.79; 0.89; 0.92) in the respective periods. In women the 0.55; 0.78) Also, in the respective periods. Given the low number of cases in women the period 1989-2003 was also considered together to obtain one SMR Black River = 0.63 and jumped SMR = 0.68. Conclusions: In men, the existence of spatial autocorrelation was identified statistically significant, with stable results in the last 2 decades analyzed. This was not observed in women. The results found in males suggest the existence a region of lower mortality from lung cancer country located on the coast

[en] Objective: To analyze trends in cancer mortality in Uruguay in the period 1989-2008. Methodology: The National Cancer Registry (NCR) collects information from cancer mortality from the death certificates: 147 631 deaths were identified in the period from cancer, which was recorded topography, sex and age. They were calculated for each year mortality rates adjusted for age (TMAE) using as standard the world population. Trends were assessed using the method and calculated the joinpoint Estimated Annual Percent Change (ESPP). Results: The TMAE presents downward trend in both sexes (ESPP = significant -0.60 in men and -0.49 In women). In the period studied, mortality presented decreasing trend when it comes to cancer breast cancer in women (ESPP -0.79, significant), and increased for prostate cancer (ESPP = 0.70) and kidney (ESPP = 1.82 and 1.71 in men and women respectively). As regards the digestive system decreased mortality observed for esophageal cancer (ESPP in = -1.93 men and women = -1.78) and stomach (ESPP = -2.22 men and women -2.24 ). Mortality for cancer of colorectum is stable in men (ESPP = 0.35 No significant (NS)) and shows a decline slight but steady in women (ESPP -0.5). As for cancers that show strong association with smoking, decreased mortality observed lung and laryngeal cancer in men (ESPP = -1.11 and -2.05 respectively), confirming the trend found between 1990 and 2001; in women there is increased mortality from lung cancer (ESPP = 2.76) that is not accompanied by increased mortality from laryngeal cancer (-0.1 ESPP = NS). Mortality from cancers oral cavity and pharynx is stable, but in women a significant increase (ESPP = 1.84) is observed when the oral cavity is analyzed in isolation (lip, tongue, gums, palate). As cervical cancer, mortality trends in 20 years is to increase (ESPP = 1.14), however, if consider only the past decade, mortality appears stabilized (ESPP = 0.57 NS). Conclusions: The overall trend of cancer mortality (all sites together) is still decreasing in Uruguay in both sexes. An increase in mortality was observed by the disease in some topographies as kidney, prostate and female lung

[en] In this paper we study the structural and electrical behavior of glass-ceramic material of general formula: xMgO (1-x) (0.5V₂O₅.0.5MoO₃)2TeO₂ (0≤ x≤0.9) through measurements of density, molar volume, oxygen packing density (OPD), differential scanning calorimetry (DSC) and Raman spectroscopy: electric behavior was studied by impedance spectroscopy. We found that magnesium cation induces the growth of slightly crystallized areas inside the material. Those nanocrystallizations were detected to a greater extent by atomic force microscopy (AFM) and in lesser extent by X-ray diffraction (XRD). Regarding the electrical measurements, it can be established that magnesium cation does not act as good ionic conductor in this material. (Author)

[en] The report contains data from experiments conducted in Mallorca in collaboration with the Year 4 Experiments of the Co-ordinated Research Programme (CRP) on Development of Medfly Female Attractants. In the last year of the program, research focused on testing three female attractants (FA-3: putrescine, ammonium acetate, and trimethylamine) in plastic International Pheromone's McPhail traps (IPMT) or Tephri traps (a Spanish version of the IPMT). Traps were either used as dry traps (provided with DDVP) or wet traps (provided with water and 0.01% surfactant). Field trials were carried out in an unmanaged citrus orchard of about 14 ha situated at sea level in the south of the island of Mallorca, about 7 km from Palma. The experimental orchard was a mixed citrus orchard of 3 ha and included tangerines, navel and navelate varieties. Two experiments were carried out. The first was with cold temperatures and a high population level (about 12 flies/trap/day) in October, November and December 1997. The second was with warm temperatures and a low population level (< 1.4 flies/trap/day) in April and May 1998. Treatments and traps included in both trials were: IPMT, FA-3, wet; IPMT, FA-3, dry; Tephri, FA-3, dry; IPMT, NU+B (IPMT trap baited with NuLure 9% and borax 3%); Tephri, FA-3, wet; and De, TML (a yellow delta trap baited with Trimedlure). The methodology followed was that described in the IAEA protocol. Fly captures were expressed as numbers of flies or flies/trap/day (F/T/D). Based on results from both studies, the Tephri, FA-3, wet was the most efficient for capturing female medflies in cool temperatures and high population conditions as well as in moderate temperatures and low population conditions. Although Tephri, FA-3, wet was the most efficient, we recommend the use of the Tephri, FA-3, dry as being the best choice for female trapping in Balearic conditions because of several drawbacks for the use of the Tephri trap as a wet trap. These included: capture of high numbers of non targeted insects (some of them beneficials); small capacity for water, which evaporated quickly under the weather conditions of Mallorca; and the size of the FA-3 lures. Trials under different conditions showed that trap design, climatic conditions, population density and fruit availability have a great influence on female capture by FA-3 baited traps. The low male capture capacity showed by FA-3 makes it adequate for using in SIT programs, although massive male releases could modify this results. The FA-3 treatments captured both mated and unmated females. Thus, these attractants may be useful to assess the sterility status of female wild population in SIT programs. FA-3 baited traps seemed to be able to detect female medfly at low population levels as well as to monitor growing population better than TML. (author)

[en] This study aims to design effective vegetation barriers, including hedges and trees, to improve air quality behind them. To achieve this objective, Computational Fluid Dynamic (CFD) modelling is applied to an avenue with hedges and trees in one sidewalk located in Pamplona (Northern Spain). Firstly, model results are evaluated by means of an experimental campaign carried out in this zone. Then, several scenarios are simulated changing the vegetation configuration in order to analyse its influence on concentration distribution behind the barrier.

[en] We show that the Dray and 't Hooft solution can be generated by a Kerr-Schild-type transformation starting with the Schwarzschild metric as a background metric. The power of this approach rests in the fact (proved by Taub) that the Einstein equations obtained by this method consist of a set of linear partial differential equations for the generating function. In this way it is possible to know the physical meaning (if any) of the solution found. We have extended the Dray and 't Hooft solution to the case with a Reissner-Nordstroem background metric
