The performance of the EU-Rotate_N model in predicting the growth and nitrogen uptake of rotations of field vegetable crops in a Mediterranean environment

The EU-Rotate_N model was developed as a tool to estimate the growth and nitrogen (N) uptake of vegetable crop rotations across a wide range of European climatic conditions and to assess the economic and environmental consequences of alternative management strategies. The model has been evaluated under field conditions in Germany and Norway and under greenhouse conditions in China. The present work evaluated the model using Italian data to evaluate its performance in a warm and dry environment. Data were collected from four 2-year field rotations, which included lettuce (Lactuca sativa L.), fennel (Foeniculum vulgare Mill.), spinach (Spinacia oleracea L.), broccoli (Brassica oleracea L. var. italica Plenck) and white cabbage (B. oleracea convar. capitata var. alba L.); each rotation used three different rates of N fertilizer (average recommended N1, assumed farmer's practice N2=N1+0·3×N1 and a zero control N0). Although the model was not calibrated prior to running the simulations, results for above-ground dry matter biomass, crop residue biomass, crop N concentration and crop N uptake were promising. However, soil mineral N predictions to 0·6 m depth were poor. The main problem with the prediction of the test variables was the poor ability to capture N mineralization in some autumn periods and an inappropriate parameterization of fennel. In conclusion, the model performed well, giving results comparable with other bio-physical process simulation models, but for more complex crop rotations. The model has the potential for application in Mediterranean environments for field vegetable production

Structure control of silica-supported mono and bimetallic Au–Pt catalysts via mercapto capping synthesis

Cataloged from PDF version of article.SiO2-supported monometallic and bimetallic platinum-gold catalysts are prepared by deposition of metal nanoparticles stabilized by mercaptopropyltriethoxysilane (MPTES) after different aging time of the solution containing metal ions and MPTES. The materials are tested in the hydrodesulfurization (HDS) reaction of thiophene and compared with corresponding catalysts prepared by the conventional deposition-precipitation (DP) method. The monometallic Pt and the bimetallic Au-Pt prepared by DP have comparable activity. With respect to the platinum catalyst prepared by DP, the corresponding platinum catalyst prepared by MPTES particle stabilization exhibits a substantial enhancement of the activity regardless the solution aging time. On the contrary, the MPTES-assisted Au-Pt catalysts have different activities, depending on the solution aging time, with the most active being the one obtained with the 5-day-aged solution. In accord with XRD, XPS, and FTIR, the aging time of the solution, through the different interaction of Pt or Au precursors with the mercapto groups, has a crucial effect on the structure and on the surface of the catalysts. The observed differences in the catalytic activity are related to the structural and compositional changes of the bimetallic particles. (C) 2012 Elsevier Inc. All rights reserved

Infant Responding to Joint Attention, Executive Processes, and Self-Regulation in Preschool Children

Infant joint attention is related to behavioral and social outcomes, as well as language in childhood. Recent research and theory suggests that the relations between joint attention and social–behavioral outcomes may reflect the role of executive self-regulatory processes in the development of joint attention. To test this hypothesis two studies were conducted. The first, cross-sectional study examined the development of responding to joint attention (RJA) skill in terms of increasing executive efficiency of responding between 9 and 18 months of age. The results indicated that development of RJA was characterized by a decreased latency to shift attention in following another person\u27s gaze and head turn, as well as an increase in the proportion of correct RJA responses exhibited by older infants. The second study examined the longitudinal relations between 12-month measures of responding to joint attention and 36-month attention regulation in a delay of gratification task. The results indicated that responding to joint attention at 12-months was significantly related to children\u27s use of three types of self-regulation behaviors while waiting for a snack reward at 36 months of age. These observations are discussed in light of a developmental theory of attention regulation and joint attention in infancy

Acute polymyositis during treatment of acute hepatitis C with pegylated interferon alpha-2b

Hepatitis C virus is not cleared after primary infection in 50-85% of subjects exposed to hepatitis C virus. Anti-viral treatment during the early phase of infection significantly enhances the likelihood of a sustained clearance of hepatitis C virus. Although, a variety of autoimmune-related side effects have been observed during interferon therapy for chronic hepatitis, immuno-mediated adverse reactions have not been reported during treatment of acute hepatitis C. We describe the case of a patient who developed acute hepatitis C virus infection and, while receiving pegylated interferon alpha-2b monotherapy, developed a severe polymyositis. This case illustrates the potential risk of autoimmunity by interferon, also for acute hepatitis, and underlines the importance of a prompt diagnosis and a rapid discontinuation of interferon treatment for an improvement of clinical outcomes. \ua9 2005 Editrice Gastroenterologica Italiana S.r.l

ANALISIS DEBIT BANJIR DAN TINGGI MUKA AIR SUNGAI TALER DI KELURAHAN PAPAKELAN KECAMATAN TONDANO TIMUR KABUPATEN MINAHASA

Sungai Taler merupakan salah satu sungai yang berada di Kecamatan Tondano Timur yang pernah meluap dan membanjiri Kelurahan Papakelan. Kejadian ini menyebabkan kerugian bagi masyarakat akibat terendamnya rumah penduduk, jalan serta lahan pertanian. Oleh karena itu dalam mengantisipasi banjir yang kemungkinan akan terjadi kelak, dibutuhkan data mengenai besarnya debit banjir dan tinggi muka air untuk penyesuaian penampang sungai Taler.Pada penelitian ini dilakukan perkiraan debit banjir rencana di Sungai Taler dengan analisis hidrologi untuk mengetahui besarnya debit banjir rencana. Simulasi elevasi tinggi muka air pada penampang sungai yang ditinjau menggunakan program komputer HEC-RAS. Analisis dimulai dengan mencari frekuensi debit menggunakan metode Log Pearson III untuk mendapatkan debit banjir rencana dengan kala ulang 2 tahun, 5 tahun, 10 tahun, 50 tahun dan 100 tahun. Adapun data debit yang digunakan berasal dari pos pemantauan debit Taler – Papakelan. Data debit yang digunakan adalah data debit maksimum sesaat tahunan dengan debit terukur tahun 2004, 2010 sampai tahun 2018. Debit puncak hasil simulasi setiap kala ulang dimasukkan dalam program komputer HEC-RAS untuk simulasi tinggi muka air pada penampang sungai yang telah diukur.Hasil simulasi menunjukkan bahwa penampang sungai Taler untuk STA 0+50, STA 0+75, STA 0+150 dan STA 0+200 pada kala ulang 2 tahun, STA 0+25 sampai STA 0+200 pada kala ulang 5 tahun, 10 tahun, 50 tahun dan 100 tahun tidak dapat menampung debit banjir yang terjadi. Hal ini disebabkan oleh tinggi muka air banjir melebihi elevasi tebing sungai. Kata kunci: Sungai Taler, Debit Banjir Rencana, Tinggi Muka Air, HEC-RAS

Fischer–Tropsch Synthesis Over Zr-Promoted Co/γ-Al2O3 Catalysts

Two Zr-modified alumina supports were synthetized containing the same amount of Zr but a different distribution of this modifier over the alumina surface. These supports, together with the unmodified alumina carrier, were used to prepare three cobalt-based catalysts which were characterized and tested under relevant Fischer–Tropsch conditions. The three catalysts presented very similar porosity and cobalt dispersion. The addition of Zr nor its distribution enhanced the catalyst reducibility. The catalyst activity was superior when using a carrier consisting of large ZrO2 islands over the alumina surface. The use of a carrier with a homogeneous Zr distribution had however, a detrimental effect. Moreover, a faster initial deactivation rate was observed for the Zr-promoted catalysts, fact that may explain this contradictory effect of Zr on activity. Finally, the addition of Zr showed a clear enhancement of the selectivity to long chain hydrocarbons and ethylene, especially when Zr was well dispersed
