The combined SHARON-Anammox process is a promising technique for nitrogen removal from wastewater streams with high ammonium concentrations. It is typically applied to sludge digestion reject water, in order to relieve the activated sludge tanks, to which this stream is typically recycled. This contribution assesses the impact of the applied control strategy in the SHARON-reactor, both on the e...
OBJECTIVE To systematically review and analyze the effects of t'ai chi on balance in older adults. METHODS The literature was searched for randomized clinical trials on the effects of t'ai chi on balance, as evaluated by direct, static, dynamic, and mixed measures. The effect sizes (ESs) on balance were calculated by using the standardized mean difference (d) and 95% confidence intervals. R...
The RecBCD enzyme of Escherichia coli functions in the seemingly disparate roles of homologous recombination and the degradation of DNA. Which of these two roles it assumes is regulated by the 8-base recombination hotspot, Chi. Using double-stranded DNA substrates that are heteroduplex at the Chi locus we have established the determinants for Chi recognition. Our results show that an actively t...
Our main, novel, result is that a certain non-central chi-squared mixture of distributions itself scaled distribution. From this and link to known on representation for central distribution, numerous further results, both old new, ensue. These include results F, F Libby–Novick distributions. The main involves all with the same degrees freedom; it also extended case where mixing distribution has...
Sarcoidosis may be affected by sex, race, and age. A Case Control Etiologic Study of Sarcoidosis (ACCESS) enrolled 736 patients with sarcoidosis within 6 mo of diagnosis from 10 clinical centers in the United States. Using the ACCESS sarcoidosis assessment system, we determined organ involvement for the whole group and for subgroups differentiated by sex, race, and age (less than 40 yr or 40 yr...
The value of creatinine height index (CHI), defined as milligrams of 24-h urinary excretion of creatinine divided by height in centimeters, was investigated on 21 healthy Japanese adults engaged in sedentary work. The average values were 10.58 in males and 6.68 in females. High partial correlation coefficients controlling sex were found among CHI, weight, fat-free mass, arm muscle area (AMA) an...
Copper nanoparticles were prepared in chitosan (CHI) membranes via reduction of CuSO4.5H2O with sodium borohydride (BH). The fabrication process was performed in two steps: (1) first adsorbing Cu(II) ions in the CHI membranes, followed by (2) a chemical reduction of the Cu(II) ions to zero-valent copper (using BH). This study used SEM, DSC, and XRD to examine the morphological, thermal and chem...
In this paper I shall present a treatment of lexical and grammatical tone and vowel length in Hausa, as implemented in an emerging bidirectional HPSG of the language based on the Lingo Grammar Matrix (Bender et al., 2002). I shall argue in particular that a systematic treatment of suprasegmental phonology is indispensible in an implemented grammar of the language, both for theoretical and pract...
the application of a comprehensive model of communicative language ability (cla) to language teaching and testing has always been an imperative in l2 education since hymess proposal of communicative competence in the 1970s. recent l2 research has clearly underscored the importance of sufficient pragmatics representation as an essential component of cla in pedagogical and testing practices in l2...
