Abstract. Measurements of mixing ratio profiles of stratospheric bromine monoxide (BrO) were made using observations of BrO otational line emission at 650.179 GHz by a balloon-borne SIS (superconductor-insulator-superconductor) submillimeterwave heterodyne receiver. The balloon was launched from Ft. Sumner, New Mexico (34°N) on 22 September 2011. Peak mid-day BrO abundance varied from 16 ± 2 ppt at 34 km to 6 ± 4 ppt at 16 km. Corresponding estimates of total inorganic bromine (Bry), derived from BrO vmr (volume mixing ratio) using a photochemical box model, were 21 ± 3 ppt and 11 ± 5 ppt, respectively. Inferred Bry abundance exceeds that attributable solely to decomposition of long-lived methyl bromide and other halons, and is consistent with a contribution from bromine-containing very short lived substances, BryVSLS, of 4 ppt to 8 ppt. These results for BrO and Bry were compared with, and found to be in good agreement with, those of other recent balloon-borne and satellite instruments.

Abstract. Measurements of mixing ratio profiles of stratospheric bromine monoxide (BrO) were made using observations of BrO rotational line emission at 650.179 GHz by a balloon-borne SIS (superconductor-insulator-superconductor) submillimeterwave heterodyne limb sounder (SLS). The balloon was launched from Ft. Sumner, New Mexico (34° N) on 22 September 2011. Peak mid-day BrO abundance varied from 16 ± 2 ppt at 34 km to 6 ± 4 ppt at 16 km.

Purpose: To estimate the cost of hospitalization associated with medication non-adherence among type 2 diabetes mellitus (T2DM) patients in a tertiary healthcare facility in Nigeria. Methods: Three hundred and fifty-four (354) medical records of T2DM patients admitted into the medical wards from 2013 to 2015 were used for the study. Medical records with history of medication non-adherence (MNA) prior to hospitalization as indicated by physicians were included in the study. Direct medical costs associated with the management of the patients during hospitalization were measured using out-of-pocket payer perspective. Pearson product moment correlation coefficient was used to determine the relationship between the variables, with p < 0.05 considered statistically significant. Results: Among the 354 admitted patients, 226 (63.8 %) had a record of MNA. The mean age was 57.5years ± 14.6. The majority of the patients (61.5 %) were either petty traders or artisans/selfemployed. Duration of hospitalization increased with increase in number of comorbid disease (Pearson product moment correlation r = 0.13 p = 0.05). Total cost incurred during hospitalization was US$146,669.3 (average, $ 650.1), of which more than one quarter was cost of medications. Cost of management and cost of laboratory investigations increased with increase in the number of co-morbid diseases (r = 0.24, p = 0.00; r = 0.2, p = 0.02, respectively). Cost of management also increased with increase in days of hospitalization (r = 0.2, p = 0.00). Conclusion: Cost of hospitalization related to non-adherence to medication is high among the studied population. There is need to work out strategies to enhance adherence among diabetes patients.

The objective: to study the effect of immunomodulators on markers of the acute inflammation phase in patients with mild community-acquired pneumonia (CAP).Subjects and methods. Patients (n = 64) with mild CAP (39.62 ± 9.82 years, CRB – 650.15 ± 0.04 scores) were enrolled in the study. The patients were divided into 2 groups: Group 1 (control) received only standard CAP therapy; in the other two groups, immunomodulators were prescribed simultaneously with standard therapy: in Group 2 – bacterial lysate (BL), in Group 3 – azoximer bromide (AB). In the patients, the blood levels of IL-6, TNF-α, C-reactive protein (CRP), lactoferrin were tested before treatment (day 1), and on days 13 and 60 of observation.Results. The initial levels of TNF-α, IL-6, CRP and lactoferrin in the patients were statistically significantly higher above normal ones. A significant decrease in the levels of TNF-α, IL-6, CRP was found in all patients on the 13th and 60th days of observation compared to the 1st day, the maximum reduction was observed in the patients receiving immunomodulators. The biggest decrease in the level of lactoferrin on the 60th day of observation was noted in the group of patients taking BL. The changes in the rate of TNF-α and IL-6 levels decrease on the 13th and 60th days were also statistically significantly more pronounced (compared to the control group). The changes in the rate of decreasing from the baseline on the 13th and 60th days in TNF-α in the BL Group made 44 [-64; -32]% and 85 [-89; -82]%; in the AB Group – 28 [-40; -20]% and 82 [-86; -80]%; in IL-6 in the BL group – 32 [-40; -18]% and 86 [-90; -85]%, in the AB group – 45 [-53; -38]% and 86 [-88; -84]%. In the control group, this parameter for TNF-α was 18 [-32; -8]% and 64 [-78; -56]%, for IL-6 – 11 [-20; -1]% and 75 [-81; -74]%.Conclusion. The addition of immunomodulators (BL, AB) to the therapy of patients with mild CAP results in statistically significant decrease in the blood levels of biomarkers of the acute inflammation phase on the 13th and 60th days.

Introduction: Ghrelin concentrations decline during puberty by an unclear mechanism. Acylated ghrelin (AG) is unstable in sampling tubes, but no standardized sampling protocol exists. We hypothesized that ghrelin levels decrease as a consequence of increased gonadotropin releasing hormone (GnRH) signalling and that the addition of a protease inhibitor to sampling tubes preserves the AG levels. Methods: In this randomized, placebo-controlled, cross-over study, 13 girls with suspected central precocious puberty were included. They performed an adjusted GnRH stimulation test twice and were given Relefact LHRH® (100 g/m2) or saline in a randomized order. Blood was sampled repeatedly for 150 min for the analysis of hormone concentrations. Oestradiol levels were only measured at baseline. The protease inhibitor 4-(2-aminoethyl) benzenesulfonyl fluoride hydrochloride (AEBSF) was added to the sampling tubes. Specific ELISA kits were used for the analysis of AG and desacylated ghrelin (DAG) levels. Results: Neither AG nor DAG levels changed after GnRH analogue injection in comparison to saline. The addition of AEBSF preserved AG levels (650.1  257.1 vs. 247.6  123.4 pg/ml, p<0.001) and decreased DAG levels (51.9 (12.5–115.7) vs. 143.5 (71.4–285.7) pg/ml, p<0.001). Both AG and DAG levels were inversely associated with insulin levels (r=-0.73, p=0.005, and r=-0.78, p=0.002, respectively). AG levels were inversely associated with oestradiol levels (rho=-0.57, p=0.041). Conclusion: Ghrelin levels do not decrease following a pharmacological dose of a GnRH analogue in the short term in girls. Addition of a protease inhibitor to the sampling tubes decreases AG degradation, resulting in preserved AG and decreased DAG levels.

PENGARUH UNSUR Zr TERHADAP PERUBAHAN SIFAT TERMAL BAHAN BAKAR DISPERSI U-7Mo-xZr/Al. Data sifat termal bahan bakar nuklir diperlukan sebagai data masukan untuk memprediksi fenomena perubahan sifat material selama proses fabrikasi maupun iradiasi di dalam reaktor nuklir. Penelitian pengaruh unsur Zr di dalam bahan bakar dispersi U-7Mo-xZr/Al (x = 1%, 2% dan 3%) terhadap perubahan sifat termal pada berbagai temperatur telah dikakukan. Tujuan penambahan unsur Zr pada penelitian adalah untuk meningkatkan stabilitas panas bahan bakar U-Mo. Analisis termal meliputi penentuan temperatur lebur, entalpi dan perubahan fasa dilakukan menggunakan Differential Thermal Analysis (DTA) pada rentang temperatur antara 30 °C hingga 1400 °C, sedangkan kapasitas panas paduan U-7Mo-xZr dan bahan bakar dispersi U-7Mo-xZr/Al menggunakan Differential Scanning Calorimeter (DSC) pada temperatur ruangan hingga 450 °C. Data analis termal dengan DTA diketahui bahwa ketiga komposisi kadar Zr menunjukkan fenomena yang mendekati sama. Pada temperatur antara 565,60 °C - 584,98 °C terjadi perubahan fasa a + d menjadi a + g, dan pada 649,22 °C - 650,13 °C terjadi peleburan matriks Al yang diikuti oleh reaksi antara matriks Al dengan U-7Mo-xZr pada temperatur 670,38 °C - 673,38 °C membentuk U(Al,Mo)x-Zr. Sementara itu, perubahan fasa α+ β menjadi β + g terjadi pada temperatur 762,08 °C - 776,33 °C dan difusi antara matriks Al dengan U-7Mo-xZr terjadi pada 853,55 °C - 875,20 °C. Setiap fenomena yang terjadi, entalpi yang ditimbulkan relatif stabil. Peleburan uranium terjadi pada 1052,42 °C - 1104,99 °C dan reaksi dekomposisi U(Al,Mo)x dan U(Al,Zr)x menjadi (UAl4, UAl3, UAl2), U-Mo, danUZr pada 1328,34 °C - 1332,06 °C. Keberadaan logam Zr di dalam paduan U-Mo meningkatkan kapasitas panas bahan bakar paduan U-7Mo-xZr/Al, semakin tinggi kadar Zr kapasitas panas meningkat yang disebabkan oleh interaksi antara atom Zr dengan matriks Al sehingga panas yang diserap oleh bahan bakar menjadi meningkatKata kunci: bahan bakar dispersi U-7Mo-xZr/Al, tranformasi fasa, entalpi, kapasitas panas. EFFECT OF THE Zr ELEMENTS WITH THERMAL PROPERTIES CHANGES OF U-7Mo-xZr/Al DISPERSION FUEL. Thermal properties data of nuclear fuel is required as input data to predict material properties change phenomenon during the fabrication process and irradiated in a nuclear reactor. Study the influence of Zr element in the U-7Mo-xZr/Al (x = 1%, 2% and 3%) fuel dispersion to changes in the thermal properties at various temperatures have been stiffened. Thermal analysis includes determining the melting temperature, enthalpy, and phase changes made using Differential Thermal Analysis (DTA) in the temperature range between 30 °C up to 1400 °C, while the heat capacity of U-7Mo-xZr alloy and U-7Mo-xZr/Al dispersion fuel using Differential Scanning Calorimeter (DSC) at room temperature up to 450 °C. Thermal analyst data DTA shows that Zr levels of all three compositions showed a similar phenomenon. At temperatures between 565.60 °C – 584.98 °C change becomes a + d to a + g phase and at 649.22 °C – 650.13 °C happen smelting Al matrix Occur followed by a reaction between Al matrix with U-7Mo-xZr on 670.38 °C – 673.38 °C form U (Al, Mo)x Zr. Furthermore a phase change α + β becomes β + g Occurs at temperatures 762.08 °C – 776.33 °C and diffusion between the matrix by U-7Mo-xZr/Al on 853.55 °C – 875.20 °C. Every phenomenon that Occurs, entalphy posed a relative stable. Consolidation of uranium Occur in 1052.42 °C – 1104.99 °C and decomposition reaction of U (Al, Mo)x and U (Al, Zr)x becomes (UAl4, UAl3, UAl2), U-Mo, and UZr on 1328,34 °C - 1332,06 °C , The existence of Zr in U-Mo alloy increases the heat capacity of the U-7Mo-xZr/Al, dispersion fuel and the higher heat capacity of Zr levels increased due to interactions between the atoms of Zr with Al matrix so that the heat absorbed by the fuel increase.Keywords: U-7Mo-xZr/Al dispersion fuel, phase transformation, entalpy, heat capacity.

The need for the identification and appropriate development of talent in organisations has led to a renewed interest in the accuracy of tools used in this context. The objectives of the study were to: (1) determine whether there is a significant difference in the growth in theoretical capability as predicted by Career Path Appreciation (CPA) 1 and CPA 2 among the sample population, (2) determine whether there is a significant difference in Mode as predicted by CPA 1 and CPA 2 among the sample population, and (3) formulate recommendations for Talent Management and Industrial and Organisational Psychology practices and future research. The CPA is a tool used for the selection and development of talent nationally and internationally. Limited recent test-retest research has been done regarding the utilisation of the CPA in this context. Scholars in the field of industrial psychology could therefore benefit from follow-up research regarding the validity and reliability of the CPA. The research design is an ex post facto correlational design using longitudinal data of a sample of convenience (N=527). Overall, the results indicated a significant correlation between CLC for CPA 1 and CPA 2 as well as between Mode for CPA 1 and CPA 2. The CPA as a measure of theoretical capability is consistently accurate between measures and can be used with confidence for the identification and development of talent within organisations.
