Bed agglomeration problems in fluidized-bed biomass combustion

Bed material agglomeration was studied experimentally in a fluidized-bed biomass combustor, Four biomass fuels, four bed materials, three bed additives, and three NOx additives were tested in a temperature range of 670-870 degreesC and at two pressure levels of 1.0 and 1.5 MPa. Two types of agglomeration were observed, a homogeneous and a heterogeneous type. The first occurred at low temperature and could be partly compensated for by erosion of the bed. The second took place at high temperatures and often involved interaction between the fuel ash and the bed material. The immobility of the bed particles made the heterogeneous agglomeration a self-accelerated process. The occurrence of hot spots in the bed was the precondition for heterogeneous agglomeration being induced. When silicon was present, alkali metals were the main contributors to heterogeneous agglomeration. Aluminum and iron compounds were able to suppress agglomeration through the high melting point of the eutectics that were formed. (Less)
New perspectives on unitary coupled‐cluster theory

The advantages and possibilities of a unitary coupled-cluster (CC) theory are examined. It is shown that using a unitary parameterization of the wave function guarantees agreement between a sum-over-states polarization propagator and response theory calculation of properties of arbitrary order, as opposed to the case in conventional CC theory. Then, using the Zassenhaus expansion for noncommuting exponential operators, explicit diagrams for an extensive and variational method based on unitary CC theory are derived. Possible extensions to the approximations developed are discussed as well. © 2006 Wiley Periodicals, Inc. Int J Quantum Chem, 2006
Verbal learning in Alzheimer's dementia

Abstract Many recent findings in Western countries suggest that episodic recall is the most sensitive discriminator between patients with mild Alzheimer disease (AD) and the normal elderly, while semantic memory tends best to differentiate between moderate and severe AD patients. The present study is the first to examine in detail the episodic memory of Chinese AD patients in Hong Kong with a locally developed list learning test, comparing procedures that do or do not encourage the use of semantic organization. The performance of 28 AD patients was compared to that of 30 normal controls. AD patients did significantly worse in terms of acquisition and retention and also benefited significantly less from external organization cues. In the discriminant function analysis, the rate of forgetting in the random condition and the total retention score in the blocked condition were found to be the best predictors for differentiating between AD patients and controls. On the other hand, in the differentiation between mild and moderate AD, semantic clustering in the blocked condition was found to be the best predictor. Results of the present study were discussed in the light of the previous findings reported in the Western countries and the neuropathological changes of AD patients. (JINS, 2003, 9, 363–375.)
Reference Materials for Geochemical Studies: New Analytical Data by ICP‐MS and Critical Discussion of Reference Values

Abundances of twenty four trace elements, including Y and fourteen rare earth elements (REE), are reported for eighty six geological reference materials and four proficiency testing samples. Analytical data were obtained by ICP-MS using solution nebulisation after mixed acid digestion (HF-HClO4) under pressure. Analysed samples cover a wide range of element concentrations and mineralogical compositions, including samples for which there are few previously published data. Precision for elemental determinations in nearly 90% of the samples analysed is better than 5%. Accuracy, estimated by comparison with data from compilations is better than 6% for well characterized reference materials. Results obtained for samples that are low in trace elements are often significantly lower than compiled reference values. A critical discussion of the compiled data sets, especially for Y and the REEs, indicates that some reference values seem to be erroneous.
Influence of Mineral Nutrients on Growth, Yield, Berry Quality, and Petiole Mineral Nutrient Concentrations of Table Grape

ABSTRACT The effect of various combination of macro (N, Mg, and K) and micronutrients (Fe and Zn) on yield, fruit quality, and tissue mineral concentrations of an important commercial table grape cultivar (Vitis vinifera cv. Bidaneh Qermez) was studied over three growing seasons of 1999–2001. Yield, fruit set, cluster weight, cluster number, berry size and quality attributes (soluble solid concentrations, pH, K-skin) were influenced by N, K, Mg, Fe, and Zn applications. Potassium application increased cluster number and weight, which resulted in a significant increase in the yield. Potassium influenced berry quality attributes more than other applied mineral elements. Yield was positively correlated to the soil total N at 30–60 cm depth. Nitrogen application increased growth of the main and lateral canes. Soil N did not correlate strongly with tissue N status.
Polish

Polish is a West Slavonic language with about 41 million speakers in Poland and approximately 10 million in diasporas. It can be described as a ‘consonantal’ language, in two respects: (a) it has a rich system of consonant phonemes, as shown in the table, and (b) it allows heavy consonant clusters, especially word-initially.
Moisture sorption characteristics of mango–soy‐fortified yogurt powder

Moisture adsorption isotherms of plain yogurt, mango–soy-fortified yogurt (MSFY) and MSFY containing 0.4% gelatin stabilizer (MSFYG) powder were determined at 20, 30, 40 and 50°C. A gravimetric static method was used under 0.11–0.81 water activity ranges for the determination of sorption isotherms that were found to be typical type II sigmoid. Experimental data were fitted to five mathematical models viz. modified Henderson, modified Chung–Pfost, Oswin, Smith and Guggenheim–Anderson–de Boer (GAB). It was found that both Oswin and GAB models were acceptable in describing equilibrium moisture content–equilibrium relative humidity (EMC–ERH) relationships for yogurt powder samples over the entire range of temperatures.
The Migration Behaviour of Transuranium Elements in Gorleben Aquifer Systems: Colloid Generation and Retention Process

The colloid generation as a part of the migration process of trans-uranic ions has been studied in the Gorlben aquifer system. From the migration study for the Gorleben repository site, typical examples are selected to demonstrate the influence of colloids. The quantification of colloid generation and its influence on the dissolution and geochemical sorption of transuranium elements are discussed.
Organizational justice–affective commitment relationship in a team sport setting: The moderating effect of group cohesion

Abstract Using organizational justice literature, the current study aimed to examine the relationship between three dimensions of organizational justice (distributive, procedural, interactional justice) and affective commitment, and to explore the moderating effect of group cohesion on the relationship between the three dimensions of justice and affective commitment in a collegiate team sport context. Data were collected from 253 college student-athletes of two Football Bowl Subdivision institutions in the Southeastern United States. Results of three hierarchical multiple regression analyses indicated that all three dimensions of justice were positively and significantly related to affective commitment. In regard to the moderating effect, group cohesion significantly moderated the distributive justice–affective commitment and the interactional–affective commitment relationships. Specifically, the two significant relationships were significantly stronger for student-athletes who reported high levels of group cohesion than their counterparts. Strategies by coaches to improve athletes’ perceptions of fairness and group cohesion and suggestions for future researches were discussed.
Energy dependence of the sputtering yield of silicon bombarded with neon, argon, krypton, and xenon ions

Sputtering yields of Si were determined for bombardment with Ne, Ar, Kr, and Xe ions at normal incidence in the energy range 0.2–20 keV under ultrahigh vacuum conditions (<10−7 Pa). Mass selection was employed and the energy spread was limited to a few electron volts. High fluences in excess of 1018 cm−2 were used to obtain stationary state yields. A special method was adopted for the yield determination, involving accurate current integration and eroded crater volume measurement with a micromechanical stylus. As a spinoff of the adopted technique, relative sputtering yields for Mo could also be determined. Our data agree with the sparse other recent experimental results. Discrepancies with older data sets are sizeable but can be attributed to our improved beam definition and better surface conditions. The measured yields are, even quantitatively, in surprisingly good agreement with predictions from Sigmund’s linear cascade theory in the low and intermediate energy range. At higher energy the yields fall .
The characteristics of bioentrepreneurs in the Australian biotechnology industry: A pilot study

Abstract In order to understand the characteristics of bioentrepreneurs, this paper seeks to identify the entrepreneurial types present in the Australian biotechnology industry by using the four-way psychological typology (Miner 2000) and identifying linkages between the four-way psychological typology and the Big Five model of personality traits. We believe this is a new approach to using psychological typology in the study of entrepreneurship by mapping with the Big Five model of personality traits. Miner's four typological types are ‘personal achievers’ (PA), ‘super sales people’ (SS), ‘expert idea generators’ (EI) and ‘real managers’ (RM). The Big Five factors are extraversion (Ex), stability/emotion stability (Es), agreeableness (Ag), conscientiousness (Co), and openness to experience (Op). By combining the entrepreneurial types and the five-factor personality traits, we can map the linkage relationships as PA-ExEsCoOp; SS-ExAgCoOp; EI-ExEsOp and RM-ExEsCoOp. In this pilot study, we find there are more ‘personal achiever’ and ‘expert idea generator’ bioentrepreneurs in the biotech industry with the linkage relationships of PA-ExEsCoOp and EI-Ex EsOp, which lead us to conclude there are strong demands for bioentrepreneurs with managerial skills, sales and marketing skills, skills in forming strategic alliance with partners and skills in securing the public and private capitals through finance channels such as public listing and venture capital. This implies that if PA entrepreneurs acquired more agreeableness personality traits and EI entrepreneurs also acquired more agreeableness and conscientiousness personality traits they would improve the ability of their businesses to attract more financial investments and form sustainable strategic alliance with partners in the Australian biotechnology industry.
Auditory and visual naming tests: Normative and patient data for accuracy, response time, and tip-of-the-tongue

Abstract Naming is typically assessed with visual naming tasks, yet, some patients with genuine word-finding difficulty (evident in auditorily based discourse) show minimal difficulty on such measures. Evidence from cortical mapping, brain imaging and neuropsychological studies suggests that auditory naming measures might provide more relevant or at least, complementary information. We developed comparable auditory and visual naming tests and present normative data for accuracy, response time, and tip-of-the-tongue responses based on 100 controls. Test validity was supported by findings that left temporal lobe epilepsy (TLE) patients (i.e., a population with expected naming difficulty) performed more poorly on auditory but not visual naming compared to right TLE patients (i.e., a population without expected naming difficulty). Internal and test–retest reliability coefficients were reasonable. Finally, test utility was assessed on an individual basis, and auditory but not visual naming performance predicted impairment.

Temperatures of Wood Particles in a Hot Sand Bed Fluidized by Nitrogen

The thermal history undergone by cylindrical beech wood particles, injected in a sand bed fluidized by nitrogen has been recorded. Experiments have been carried out by varying particle diameter (d = 2−10 mm) and bed temperature (Tr = 712−1107 K). The rate of volatile release becomes significant for temperatures above 625−650 K and is always completed for temperatures below 675−825 K. Devolatilization causes a strong reduction in the heating rate which, at the particle center and for the most intense reaction activity, is comprised between 0 and 25 K/s. For the conditions typical of fast pyrolysis (bed temperatures of 800−1100 K and particle sizes of 2−6 mm), the yields of char are 10−18% and the devolatilization times (corresponding to a conversion of 95%) 18−45s. Furthermore, in qualitative agreement with previous analyses carried out for coal particles, these are well predicted by an empirical power-law relation: tv = 0.8e1525/Trd1.2 s, over the entire range of experimental conditions examined.
Preparation of highly porous TiO2 nanotubes and their catalytic applications

A simple procedure for preparing highly porous TiO2 nanotubes is reported. The nanotubes were prepared in the form of a nonwoven mat by emulsion electrospinning a solution containing poly(vinyl pyrrolidone), titanium tetraisopropoxide and oil, followed by calcination in air at 500 °C. The mixed crystalline material comprised anatase and rutile TiO2 particles, whose diameters were about 11 nm and 21 nm, respectively. The highly porous TiO2 nanotube membranes, which had large specific surface areas and excellent ratios of anatase phase to rutile phase, were shown to have excellent catalytic activities. Also the mixture of crystal forms improved the efficiency of photocatalysis because at the mixed interface electrons and holes are separated effectively. The new method for producing highly porous TiO2 nanotubes is versatile and could be extended to the fabrication of various types of highly porous nanotubes.
Factors that Influence the Speed of Occurence of Senile Cataracts in South Sumatra

Introduction. Cataracts are any condition of opacity in the lens that can occur due to the hydration (fluid addition) of the lens, the lens protein denaturation or the consequences of both. Factors that can affect the development rate of the opacity of the lens such as diabetes mellitus, hypertension, certain medications, the B ultraviolet rays from sunlight, toxic effects of smoking, alcohol, less vitamin E, and chronic inflammation in the eyeball.Methods. The type of research is observational analytical with a cross-sectional design. This study was held in August to December in 2019 in Eye hospital in South Sumatra with sampling as many as 234 patients from the medical record. Data is processed using SPSS. The Chi-square test is conducted to determine the relationship of factors that affect the rate of senile cataract in Eye Hospital in South Sumatera Province. Results. From 234 patients, as many as 177 patients (75.6%) with mature cataract and 57 patients (24.4%) with immature cataract. There is no meaningful relation between senile cataract and hypertension (p = 0,068; OR = 1,084; 95% CI = 0,589-1,995). There is no meaningful relation between senile cataract and diabetes mellitus (p = 1.808; OR = 1,876; 95% CI = 0,741-4,747). There is no meaningful relation between senile cataract and gender (p = 0.51; OR = 0,933; 95% CI = 0,514-1,696). There is no meaningful relation between the senile cataract and age (p = 0,784; OR = 1,319; 95% CI; 0,714-2,437). Conclusion. There is no significant relationship between senile cataract occurence, hypertension, diabetes mellitus, gender and age.
Polydorid species (Polychaeta: Spionidae) in Japan, with descriptions of morphology, ecology and burrow structure. 2. Non-boring species

A total of 11 polydorid species of the family Spionidae were extracted from non-calcareous substrata from Japan. The polydorids were: one Polydora sp. , Polydora cornuta; three Dipolydora spp. , Dipolydora quadrilobata, D. cardalia, D. socialis; one Carazziella sp. , Carazziella spongilla; one Boccardiella sp. , Boccardiella hamata; two Boccardia spp. , Boccardia perata, B. proboscidea; three Pseudopolydora spp. , Pseudopolydora cf. kempi, P. antennata, P. paucibranchiata. All inhabited mud deposits including mud in crevices of calcareous substrata, sponge and sandstone rocks, and were never found in self-excavated burrows in calcareous substrata. This study attempts to summarize and discuss the taxonomic, morphological, and behavioural characteristics of these non-boring species inhabiting Japanese waters and to compare them with the previously known boring species. The 11 non-boring species belonged to six genera. Thus their taxonomic and morphological variability was higher than those of boring species, which belonged only to three genera. A generic overview suggests that some genera contain many species capable of boring and others contain many species incapable of boring. Branchial blood vessels were thick and conspicuous in non-boring species. Moreover, they showed high crawling activity and a strong, vigorous palp movement. These observations suggest a possible link between boring activity and the morphology and behaviour in polydorids. In addition, Polydora cornuta, Dipolydora quadrilobata, D. cardalia, D. socialis, Boccardia perata and Pseudopolydora cf. kempi are new to Japan.
The Influence of pH on Localized Corrosion Behavior of X65 Carbon Steel in CO2-Saturated Brines

Pitting and localized corrosion of carbon steel is considered to be a complex process influenced by a wide range of parameters such as temperature, bulk solution pH, and chloride ion concentration. Solution pH is known to influence corrosion product characteristics and morphology in CO2- and H2S-containing corrosion systems. However, from the perspective of pitting corrosion in CO2-saturated environments, the extent to which bulk pH of solutions and the presence of corrosion products influence localized attack is still not clearly understood. This paper presents an investigation into the role of pH on the characteristics of corrosion product and pitting corrosion behavior of X65 carbon steel (UNS K03014) in CO2-saturated brine. Pitting corrosion studies were conducted over 168 h at 50°C in 3.5 wt% NaCl solutions at different bulk pH (buffered to pH values of 6.6 and 7.5 in some cases) in order to understand and correlate the role of pH on corrosion product morphology, chemistry, initiation, and propagatio.
Discectomy and Fusion Operation and Severity of Cage Subsidence Following Anterior Cervical Analysis of the Variables Affecting the Incidence, Location,

Background: For surgical management of degenerative cervical spine disease with myeloradiculopathy, stand-alone cages are frequently used in 1-and 2-level anterior cervical discectomy and fusion (ACDF) operations with a paucity of literature on factors influencing cage subsidence. The aim of this study was to analyze the variables affecting the incidence, location, and severity of cage subsidence. Methods: Retrospective review of prospectively collected data of 77 patients (95 levels) undergoing ACDF surgery was conducted. Variables analyzed were age, gender, sagittal alignment, maximum disc height (superior, inferior, and procedure levels), cage size, shape, location, degree of subsidence (minor , 2 mm, mild 2–4 mm, moderate 5–7.5 mm, severe . 7.5 mm) and location of subsidence. Results: The incidence of cage subsidence was 34% (32 levels), and 91% were minor or mild. Significantly lower mean maximum height of the inferior disc compared to the nonsubsidence group (5.17 versus 5.96; P ¼ 0.0025) was recorded. Significantly greater incidence of subsidence (40%) was recorded in patients with abnormal cervical spine alignment (focal or diffuse kyphosis) versus 18% with normal alignment ( P ¼ 0.02). Greater incidence of subsidence was recorded with more anterior positioned cages (52%; p ¼ 0.01). No statistical significance was found for age, gender, superior disc height, or cage shape/size. Conclusions: Greater incidence of cage subsidence is significantly associated with a lower maximum disc height of the disc below the operated level ( , 5.5 mm), abnormal sagittal alignment, and more anteriorly positioned cages. We found that the vast majority of cage subsidence was focal, minor to mild, without having any immediate or late clinical implications in terms of need for revision surgery.
Evaluation of a [67Ga]-Thiosemicarbazone Complex as Tumor Imaging Agent

[67Ga]labeled 2-acetylpyridine 4,4-dimethylthiosemicarbazone ([67Ga]- [APTSM2]2+) was prepared using freshly prepared [67Ga]GaCl3 and 2-acetylpyridine 4,4-dimethylthiosemicarbazone (APTSM2) for 30 min at 90°C (radiochemical purity: >97% ITLC, >98% HPLC, specific activity: 15–20 Ci/mmol). Stability of the complex was checked in human serum for 37°C. The biodistribution of the labeled compound in vital organs of normal and fibrosarcoma bearing mice were compared with that of free Ga3+ cation up to 24h. Initial SPECT images and biodistribution results showed significant tumor uptake in fibrosarcoma-bearing mice after 2 hour post injection.

This study investigates the dominant orientations of lineament features and the relationship between these trends and the spatial orientation of tectonic structures in the transition zone of the Congo craton and the Pan African belt in South Cameroon area. Landsat 8 OLI/TIRS and hill-shaded images, constructed from 30 m-resolution SRTM-DEM data, were used for automatically extracting and mapping geological lineaments. Lineament features were analyzed by means of azimuth frequency and length density distributions. Three major sets of lineaments trending W–E, ENE-WSW and WNW-ESE are identified in the South Cameroon area. These trends are probably related to repeated reactivation of pre-existing crustal structures during Eburnean and Pan-African tectonic episodes. The lineaments were formed under the compressional tectonic stress regimes generated during these tectonic events.
