Factorization Results with Combinatorial Proofs
Authors: Corrádi Keresztély , Szabó Sándor 
Published: January 2010

AbstractTwo results on factorization of finite abelian groups are proved using combinatorial character free arguments. The first one is a weaker form of Rédei's theorem and presented only to motivate the method. The second one is an extension of Rédei's theorem for elementary 2-groups, which was originally proved by means of characters.
Longitudinal Assessment of Intellectual Achievement in Patients With Classical Galactosemia

Published: January 2010

OBJECTIVE:To conduct a longitudinal assessment of long-term cognitive outcome in patients with classical galactosemia.METHODS:Inclusion criteria were (1) previous assessment of IQ dating back &gt;10 years with tests being comparable with the recent German tests HAWIK-III and HAWIE-R, (2) absence of illnesses other than galactosemia, (3) absence of foreign language problems, (4) enzymatic-metabolic proof of classical galactosemia, (5) compliance with dietary therapy, and (6) written informed consent. Twenty-three patients who fulfilled these criteria were found. They underwent the first IQ test at a mean age of 11 ± 5 years and the second 13.6 to 15.5 years later at a mean age of 26 ± 5 years. Results were corrected for the obsolescence of test norms (Flynn effect).RESULTS:Mean total IQ scores on the first and second tests were 78 ± 14 and 73 ± 15, respectively, and not significantly different. IQ scores in the average range were observed for 7 patients on the first test and for 5 patients on the second test. For 17 patients, the intraindividual IQ scores remained essentially unchanged. Five patients showed a decrease and 1 an increase of the IQ score over time. No consistent pattern of change was found with respect to performance or verbal IQ subscores or in achievements in the individual subtest.CONCLUSIONS:The results confirm the presence of reduced cognitive ability in classical galactosemia and present evidence for an absence of substantial galactosemia-induced aggravation of this impairment with increasing age, at least in patients from 4 to 40 years of age. It remains to be clarified whether a reduction of cognitive function in galactosemia may be initiated by an in utero toxicity of endogenously formed galactose and which role such a process may play in the development of intellectual deficiencies that are later maintained throughout life.
Maternal Practices That Influence Hispanic Infants' Health and Cognitive Growth

Published: January 2010

OBJECTIVES:
Infants born to immigrant mothers, including Hispanic mothers, display birth weight and mortality advantages, compared with other disadvantaged groups. We examined prenatal biological factors and maternal practices that account for this advantage. Then we estimated the extent to which healthy birth outcomes, along with maternal and family factors, contribute to the health and cognitive functioning of Hispanic infants.

METHODS:
A representative US sample of 8114 newborns, including 1450 newborns of Hispanic mothers, was drawn randomly in 2001. We compared the mean attributes of infants in subgroups that vary in maternal practices, family attributes, and acculturation levels. We accounted for variations in newborns' gestational age and size for gestational age and their health status and cognitive functioning at 9 months of age.

RESULTS:
Mexican-heritage and less-acculturated mothers were no more likely than white mothers to bear premature or small-for-gestational age infants, despite large social class disparities, which was explained in part by Hispanic women's low level of prenatal tobacco use. Parenting practices and lower class status of Hispanic mothers then began to slow infants' cognitive development, compared with white infants, because of weaker maternal education and cognitive facilitation during interaction tasks and larger family size.

CONCLUSIONS:
These findings extend earlier research, detailing healthy births among most immigrant Hispanic women. Robust birth outcomes contribute to the early health and cognitive growth of Hispanic infants, but risk factors linked to maternal and home practices overtake these early protective factors by late infancy. Robust births and early health indicators displayed by Hispanic infants should not distract pediatricians from attending to uneven cognitive growth.
Effectiveness of the Pentavalent Rotavirus Vaccine in Preventing Gastroenteritis in the United States
Authors: Wang Florence T. , Mast T. Christopher , Glass Roberta J. , Loughlin Jeanne , Seeger John D. 
Published: January 2010

OBJECTIVE:
In clinical trials, the pentavalent rotavirus vaccine (RV5) was efficacious in preventing severe rotavirus gastroenteritis (RGE) and related health care encounters. We assessed the vaccine effectiveness (VE) of RV5 among US infants during the first 2 rotavirus seasons after vaccine licensure.

METHODS:
Using a large, national, health insurance claim database, we monitored 2 cohorts of infants (infants who received 3 doses of RV5 and a concurrent group of infants who received 3 doses of diphtheria-tetanus-acellular pertussis vaccine but did not receive RV5) through the 2007 and 2008 rotavirus seasons (January 1 to May 31), to identify cases of RGE and all-cause acute gastroenteritis (AGE) resulting in medical care encounters. We estimated the VE in reducing hospitalizations, emergency department (ED) and physician office visits, and health care resource utilization, as measured by days and costs of hospitalizations and ED visits.

RESULTS:
A total of 33 140 RV5-vaccinated infants and 26 167 infants in the concurrent diphtheria-tetanus-acellular pertussis vaccine cohort were included in the analysis. The VE against RGE (hospitalization and ED) was 100% (95% confidence interval [CI]: 87%–100%), whereas the VE against AGE was 59% (95% CI: 47%–68%). In the outpatient setting, the VE against RGE and AGE was 96% (95% CI: 76%–100%) and 28% (95% CI: 22%–33%), respectively. There was a complete (100%) reduction in RGE hospitalization and ED visit days and a 100% reduction in costs. RV5 was associated with a 66% decrease in AGE-related hospitalization and ED visit days and a 74% reduction in costs.

CONCLUSIONS:
In this first nationwide study evaluating VE under conditions of routine use, RV5 was highly effective in preventing RGE and AGE and in reducing health care resource utilization. Further research is needed to assess VE with an incomplete rotavirus vaccination regimen.

Tait's conservative extension theorem revisited
Authors: Akiyoshi Ryota 
Published: January 2010

AbstractThis paper aims to give a correct proof of Tait's conservative extension theorem. Tait's own proof is flawed in the sense that there are some invalid steps in his argument, and there is a counterexample to the main theorem from which the conservative extension theorem is supposed to follow. However, an analysis of Tait's basic idea suggests a correct proof of the conservative extension theorem and a corrected version of the main theorem.
A monotonicity theorem for dp-minimal densely ordered groups
Authors: Goodrick John 
Published: January 2010

AbstractDp-minimality is a common generalization of weak minimality and weak o-minimality. IfTis a weakly o-minimal theory then it is dp-minimal (Fact 2.2), but there are dp-minimal densely ordered groups that are not weakly o-minimal. We introduce the even more general notion of inp-minimality and prove that in an inp-minimal densely ordered group, every definable unary function is a union of finitely many continuous locally monotonic functions (Theorem 3.2).
Normal triangulations in o-minimal structures

Published: January 2010

AbstractLet be an o-minimal structure over a real closed field R. Given a simplicial complex K and some definable subsets S1, …, Sl of its realization ∣K∣ in R we prove that there exist a subdivision K′ of K and a definable triangulation φ′: ∣K′∣ → ∣K∣ of ∣K∣ partitioning S1, …, Sl with φ′ definably homotopic to id∣K∣. As an application of this result we obtain the semialgebraic Hauptvermutung.

We prove that ifGacts definably on a definable set ofUр-rank 1, then, under some general assumption about this action, there is an infinite field interpretable in. We conclude that ifGis not solvable-by-finite and it acts faithfully and definably on a definable set ofUр-rank 1, then there is an infinite field interpretable in. As an immediate consequence, we get that ifGhas a definable subgroupHsuch thatUр(G) =Uр(H) + 1 andG/⋂g∈GHgis not solvable-by-finite, then an infinite field interpretable inalso exists.

Published: January 2010

Seaweeds are used many folds for animal and human food, soil manure, salt extractions (soda, iodine etc.) and colloid production (agar-agar, alginate, carrageenan, furcellaran etc.), cosmetics and pharmaceutics. These represent important economical resources in world wide, where they are not only largely harvested but also intensively and largely employed in the human nutrition. Mineral composition of seaweeds was found relatively higher as compared to the land vegetables. Keeping the significance in mind, in current work nine seaweeds such as Chaetomorpha spp., Cladophora facicaularis, Ulva lactuca, Caulerepa racemosa, Caulerepa sertularioides, Valoniopsis pachynema, Sargassum ilicifolium, Sargassum polycustum and Porphyra vietnamensis growing along the Bet Dwarka, West Coast of Gujarat, India were collected and analyzed for nutrient / mineral composition like Mg, K, Na, Ca, S, N, Cl and P, ash content and calorific value. The nutrient concentration ranges found for each sample, were as follows: Mg, 70.4-248.1; K, 16.6-128.04; Na, 78.7-129.07; Ca, 121-476.67; S, 101.11-214.99; N, 34.31-56.34; Cl, 26.12-235.66; and P, 0.78-1.53 expressed in g/100 g dry weight. Calorific content and ash content, ranged between 11.3-22.6 MJ/Kg and 23.0-41.9 g/100 g dry weight, respectively. Calorific content was negatively correlated with ash content and nutrient composition, but ash content was found to be positive correlation with mineral composition of selected sea weeds.

Loss of vision in a bleeding peptic ulcer patient following resuscitation - an unusual cause of non-arteritic anterior ischaemic optic neuropathy
Authors: Majumder Md Shafayet Hasan 
Published: January 2010

A 55-year old male, known to have peptic ulcer disease for 4 years, started haematamesis and melaena in a rural area of Bangladesh and was admitted into hospital with circulatory collapse. He was resuscitated with 8 units of whole blood transfusion and became stable. But he developed sudden loss of vision and fundoscopy revealed bilateral papilloedema but CT scan appeared normal. Clinical and ophthalmological evaluation was consistent with non-arteritic anterior ischaemic optic neuropathy.

A CONTRIBUTION TO THE INSECT FAUNA OF TIMAGAMI
Authors: Brown A. W. A. 
Published: January 2010

Lake Timagami is the centre of one of the few extensive pine forests of the Canadian Zone which still remain. The virgin conditions of half a continent make their last stand against lumbering and settlement in such regions as this; a study of its fauna seems, therefore, imperative to Canadian biologists.This collection, of which a list follows, was made in the summer of 1932 though unfortunately no collecting was done during the period from June 12 to July 21. No attempt at life-history notes is made, but macro- and micro habitat of the adult are recorded where possible. Localities are indicated by initials and described separately.
An Explicit Treatment of Cubic Function Fields with Applications
Authors: Landquist E. , Rozenhart P. , Scheidler R. , Webster J. , Wu Q. 
Published: January 2010

AbstractWe give an explicit treatment of cubic function fields of characteristic at least five. This includes an efficient technique for converting such a field into standard form, formulae for the field discriminant and the genus, simple necessary and sufficient criteria for non-singularity of the defining curve, and a characterization of all triangular integral bases. Our main result is a description of the signature of any rational place in a cubic extension that involves only the defining curve and the order of the base field. All these quantities only require simple polynomial arithmetic as well as a few square-free polynomial factorizations and, in some cases, square and cube root extraction modulo an irreducible polynomial. We also illustrate why and how signature computation plays an important role in computing the class number of the function field. This in turn has applications to the study of zeros of zeta functions of function fields.
Degenerate p-Laplacian Operators and Hardy Type Inequalities on H-Type Groups
Authors: Jin Yongyang , Zhang Genkai 
Published: January 2010

AbstractLet 𝔾 be a step-two nilpotent group of H-type with Lie algebra 𝔊 = V ⊕ t. We define a class of vector fields X = {Xj} on 𝔾 depending on a real parameter k ≥ 1, and we consider the corresponding p-Laplacian operator Lp,ku = divX(|∇Xu|p−2∇Xu). For k = 1 the vector fields X = {Xj} are the left invariant vector fields corresponding to an orthonormal basis of V; for 𝔾 being the Heisenberg group the vector fields are the Greiner fields. In this paper we obtain the fundamental solution for the operator Lp,k and as an application, we get a Hardy type inequality associated with X.
Synthesis of mechanical driver and power generation configurations, Part 1: Optimization framework
Authors: Del Nogal Frank L. , Kim Jin‐Kuk , Perry Simon , Smith Robin 
Published: January 2010

AbstractThis article presents a novel, systematic, and robust procedure for driver and power plant selection based on mathematical programming. The discrete nature of gas turbines is considered as gas turbine drivers and gas turbine‐based power plants are selected from a group of candidates. Plant availability with considering parallel compression has also been included, which allows a more comprehensive exploitation of the trade‐offs between capital costs, operating costs, and availability. When neglecting process heating and any steam equipment, the formulation can be applied to heavily power dominated processes, such as LNG. However, a more comprehensive formulation, allowing waste heat recovery and the integration with a multilevel steam system, is also proposed to produce more thermally efficient systems. This approach proved to be flexible and robust and is the first in producing solutions ranging from no‐steam to all‐steam systems, including all‐gas turbine, all‐motor and hybrid gas turbine/motor/steam systems. © 2010 American Institute of Chemical Engineers AIChE J, 2010
Synthesis of mechanical driver and power generation configurations, Part 2: LNG applications
Authors: Del Nogal Frank L. , Kim Jin‐Kuk , Perry Simon , Smith Robin 
Published: January 2010

AbstractOptimization framework for the synthesis of power systems has been presented in Part 1 of this article, which systematically identifies the most cost‐efficient number, type, and model of mechanical drivers, together with optimal arrangement for compressor stage, helper motors or generators, and power plants. The developed methodology is applied to an LNG case study in which optimal and near‐optimal systems at various economic scenarios are identified. Also, a systematic methodology for the integrated design of refrigeration and power systems has been addressed to improve the overall design of low temperature processes. Additional key degrees of freedom such as stage pressure ratios and plant capacity are optimized, alongside other design variables, which provide greater flexibility in the matching of power supply and demands. This strategy is applied to an LNG case study and shows the convenience of this approach as the interactions between the refrigeration and power systems are systematically exploited. © 2010 American Institute of Chemical Engineers AIChE J, 2010
