Data quality objectives for the second K West fuel examinations

The Data Quality Objectives (DQOS) were established for the examinations of the second group of K West fuel samples. The examinations will expand the initial understanding obtained for fuel stored in closed canisters with emphasis on whole element drying and conditioning testing and Thermo-Gravimetric Analysis (TGA) for oxidation behavior, drying, and hydrogen release. The laboratory examinations addressed in this DQO take into account the extent and diversity of the fuel damage as indicated by previous in-basin examinations. A total of fifteen fuel elements are identified for laboratory examinations. Three of these elements are designated for surface coating examinations and two elements are designated for examination of subsurface sludge accumulations and for sectioning of small samples for TGA measurement

Strategy for phase 2 whole element furnace testing K West fuel

A strategy was developed for the second phase of the whole element furnace testing of damaged fuel removed from the K West Basin. The Phase 2 testing can be divided into three groups covering oxidation of whole element in moist inert atmospheres, drying elements for post Cold Vacuum Drying staging tests, and drying additional K West elements to provide confirmation of the results from the first series of damaged K West fuel drying studies

Strategy for thermo-gravimetric analysis of K East fuel samples

A strategy was developed for the Thermo-Gravimetric Analysis (TGA) testing of K East fuel samples for oxidation rate determinations. Tests will first establish if there are any differences for dry air oxidation between the K West and K East fuel. These tests will be followed by moist inert gas oxidation rate measurements. The final series of tests will consider pure water vapor i.e., steam

Data quality objectives for the reaction kinetics studies of K West fuel samples

The Data Quality Objectives (DQOs) were established for the reaction kinetics studies of the first group of fuel samples shipped from the K West Basin to the Hanford 327 Building hot cells for examinations. A Thermo-Gravimetric Analysis (TGA) system was selected for these measurements and associated hydrogen release and ignition temperature testing. These examinations are an extension of the conditioning testing of sibling samples described in WHC-SD-SNF-DQO-004, Data Quality Objectives for the Initial Fuel Conditioning Examinations

In Vitro Culture of Seaweed Kappaphycus alvarezii under Different Formulation of Growth Stimulating Substances and Culture Media

This study aims at obtaining a sustainably superior seed stock following the characteristics of the parent plant, determining the best formulation of the growth stimulating substance. In general, cytokinin and auxin combination was used, but this study also added with the combination of cytokinin and giberelin and cytokinin and abscisic acid (AA).Parameters measured were bud length, number of buds, and survival rate. Bacterial Vibrio sp test was also done as a cause of the explant mortality. Results showed that the longest bud was recorded in treatment C (S+A 1:2.5) cultured in a jar, 1.343 mm long, 38% of survival, while the highest number of buds was found in treatment B (S+A 1 : 2) 8.86. The shortest bud was recorded in treatment J (S + AA 1:2.5) cultured in a jar, 0.093 mm long, 2.64 buds, 10% of survival, while the explant cultured in the bottle had a length of 0.051 mm long, 1.50 buds, 4% of survival. As conclusion, the best growth stimulating substance was found in the treatment C for the bud length and the survival rate, while the best number of bud was recorded in the treatment B. The best culture tank was topless bottle (aerated). In vitro culture could also use S + G formulation. The explant mortality was caused by Vibrio charchariae. The use of S + AA formulation had lower growth than that of control treatment.Keywords :in vitro, growth stimulating substance, culture media, Kappaphycus alvarezii, Vibrio charchariae ABSTRAKPenelitian ini bertujuan untuk memperoleh benih unggul secara berkelanjutan yang mengikuti karakteristik dari tanaman induk, menentukan formulasi terbaik dari substansi pertumbuhan merangsang. Secara umum, kombinasi sitokinin dan auksin digunakan, tetapi penelitian ini juga menambahkankombinasi sitokinin, giberelin, sitokinin dan asam absisat (AA). Parameter yang diukur adalah panjang tunas, jumlah tunas, dan tingkat kelangsungan hidup. Bakteri Vibrio Uji sp juga dilakukan sebagai penyebab kematian eksplan . Hasil penelitian menunjukkan bahwa tunas terpanjang terdapat pada perlakuan C (S + A 1: 2,5)  kultur dalam toples, 1,343 mm, 38% hidup, sementara jumlah tertinggi tunas ditemukan pada perlakuan B (S + A 1: 2) 8.86 . Jumlah tunas paling sedikit terdapat pada perlakuan J (S + AA 1: 2,5) yang dikultur dalam toples, 0,093 mm, 2,64 tunas, 10% hidup, sedangkan eksplan yang dikultur dalam botol memiliki panjang 0.051 mm, 1. 50 tunas , 4% bertahan hidup. Sebagai kesimpulan, pertumbuhan terbaik merangsang zat ditemukan dalam perlakuan C untuk panjang tunas dan tingkat kelangsungan hidup, sementara jumlah tunas terbanyak ditemukan pada perlakuan B. Penggunaan wadah budaya terbaik adalah topless yang diaerasi. Kultur in vitro juga dapat menggunakan formulasi S + G. Kematian eksplan disebabkan oleh Vibrio charchariae .

Performance characteristics and blood profile of West African dwarf goats fed diet containing graded level of malted sorghum sprout mixed with pineapple waste based diet

A twelve week trial was investigated to evaluate performance and blood profile of West African dwarf (WAD) goats fed malted sorghum sprout with pineapple waste (MSPW) based diet. The malted sorghum sprout and pineapple waste was at ratio 1:2 (weight/weight) respectively. Sixteen WAD goats with average initial weight of 6 ±1.20 kg were allotted into four dietary  treatments in a Completely Randomized Design. Four diets were formulated to contain 0%, 20%, 40% and 60% of MSPW. Data were collected on growth performance and blood profile. Result revealed that there was no significant (P>0.05) differences on all the growth performance parameters measured. The highest value of average daily weight gain (19.21 g/day) was observed in goats fed 20% MSPW while the lowest value was obtained in goats fed 40% MSPW Goats placed on 20% MSPWhad the best feed conversion ratio  value . (17.15). No significant differences (P>0.05) were observed on all blood profile parameters measured except the albumin and creatinine. The albumin and creatinine values ranged from 2.63-3.52 g/dl and 0.90- 1.50mg/dl  respectively. It can be concluded that WAD goats fed 20% MSPW based diet yielded best results in terms of performance and there was no detrimental effect on their blood profile.Keywords: Malted Sorghum Sprout, Pineapple, Performance, Seru

WISP genes are members of the connective tissue growth factor family that are up-regulated in Wnt-1-transformed cells and aberrantly expressed in human colon tumors

Wnt family members are critical to many developmental processes, and components of the Wnt signaling pathway have been linked to tumorigenesis in familial and sporadic colon carcinomas. Here we report the identification of two genes, WISP-1 and WISP-2, that are up-regulated in the mouse mammary epithelial cell line C57MG transformed by Wnt-1, but not by Wnt-4. Together with a third related gene, WISP-3, these proteins define a subfamily of the connective tissue growth factor family. Two distinct systems demonstrated WISP induction to be associated with the expression of Wnt-1. These included (i) C57MG cells infected with a Wnt-1 retroviral vector or expressing Wnt-1 under the control of a tetracyline repressible promoter, and (ii) Wnt-1 transgenic mice. The WISP-1 gene was localized to human chromosome 8q24.1-8q24.3. WISP-1 genomic DNA was amplified in colon cancer cell lines and in human colon tumors and its RNA overexpressed (2- to >30-fold) in 84% of the tumors examined compared with patient-matched normal mucosa. WISP-3 mapped to chromosome 6q22-6q23 and also was overexpressed (4- to >40-fold) in 63% of the colon tumors analyzed. In contrast, WISP-2 mapped to human chromosome 20q12-20q13 and its DNA was amplified, but RNA expression was reduced (2- to >30-fold) in 79% of the tumors. These results suggest that the WISP genes may be downstream of Wnt-1 signaling and that aberrant levels of WISP expression in colon cancer may play a role in colon tumorigenesis

Parameters of the Magnetic Flux inside Coronal Holes

Parameters of magnetic flux distribution inside low-latitude coronal holes (CHs) were analyzed. A statistical study of 44 CHs based on Solar and Heliospheric Observatory (SOHO)/MDI full disk magnetograms and SOHO/EIT 284\AA images showed that the density of the net magnetic flux, $B_{{\rm net}}$, does not correlate with the associated solar wind speeds, $V_x$. Both the area and net flux of CHs correlate with the solar wind speed and the corresponding spatial Pearson correlation coefficients are 0.75 and 0.71, respectively. A possible explanation for the low correlation between $B_{{\rm net}}$ and $V_x$ is proposed. The observed non-correlation might be rooted in the structural complexity of the magnetic field. As a measure of complexity of the magnetic field, the filling factor, $f(r)$, was calculated as a function of spatial scales. In CHs, $f(r)$ was found to be nearly constant at scales above 2 Mm, which indicates a monofractal structural organization and smooth temporal evolution. The magnitude of the filling factor is 0.04 from the Hinode SOT/SP data and 0.07 from the MDI/HR data. The Hinode data show that at scales smaller than 2 Mm, the filling factor decreases rapidly, which means a mutlifractal structure and highly intermittent, burst-like energy release regime. The absence of necessary complexity in CH magnetic fields at scales above 2 Mm seems to be the most plausible reason why the net magnetic flux density does not seem to be related to the solar wind speed: the energy release dynamics, needed for solar wind acceleration, appears to occur at small scales below 1 Mm.Comment: 6 figures, approximately 23 pages.
