EFFECT OF POZZOLAN PROPERTIES ON THE PROPERTIES OF BUILDING COMPOSITES

Pozzolans were used by ancient civilizations to enhance the properties of mortars and concrete and are now regaining popularity as sustainable, environmentally-friendly alternatives to cement. This paper studies the relationships amongst some properties of nine pozzolans and their impact on compressive strength and setting time of the resultant composites. Its objective is to assist in making informed choices in the selection of pozzolans for the production of mortars and concrete. Results indicate that each pozzolan has a specific water demand that increases with its specific surface area; and that a high water demand by the pozzolan slows down the setting of the paste but does not undermine the strength of the composite. It was also found that specific surface has a much greater influence on the water demand of the paste than particle size or lime:pozzolan ratio. The results exposed the adverse effect of a small water increase on setting time, and the lack of relationship between setting and reactivity. It was evidenced that the pozzolans accelerate the final set of lime by at least 40%, and that the specific surface area of the pozzolan and its amorphousness are the most important variables affecting reactivity and strength. Strength development and reactivity results allowed determining the most reactive pozzolans.
Weighted Szeged Index of Graphs

The weighted Szeged index of a connected graph G is dened as Szw(G) = Σe=uv 2E(G)(dG(u) + dG(v))nGu(e) nGv(e); where nGu (e) is the number of vertices of G whose distance to the vertex u is less than the distance to the vertex v in G: In this paper, we have obtained the weighted Szeged index Szw(G) of the splice graph S(G1;G2; y; z) and link graph L(G1;G2; y; z).
Laboratory simulation for the aqueous OH-oxidation of methyl vinyl ketone and methacrolein: significance to the in-cloud SOA production

Abstract. Increasing evidence suggests that secondary organic aerosol (SOA) is formed through aqueous phase reactions in atmospheric clouds. In the present study, the aqueous oxidation of methyl vinyl ketone (MVK) and methacrolein (MACR) via OH radical were investigated, with an emphasis on the composition and variation of small-molecular-weight organic products. In addition, high-molecular-weight compounds (HMWs) were found, interpreted as the ion abundance and time evolution. Our results provide, for the first time to our knowledge, experimental evidence that aqueous OH-oxidation of MVK contributes to SOA formation. Further, a mechanism primarily involving radical processes was proposed to gain a basic understanding of these two reactions. Based on the assumed mechanism, a kinetic model was developed for comparison with the experimental results. The model reproduced the observed profiles of first-generation intermediates, but failed to simulate the kinetics of most organic acids mainly due to the lack of chemical kinetics parameters for HMWs. A sensitivity analysis was performed in terms of the effect of stoichiometric coefficients for precursors on oxalic acid yields and the result indicates that additional pathways involving HMWs chemistry might play an important role in the formation of oxalic acid. We suggest that further study is needed for better understanding the behavior of multi-functional products and their contribution to the oxalic acid formation.

Qualitative Research and the Generalizability Question: Standing Firm with Proteus

Qualitative studies are tools used in understanding and describing the world of human experience. Since we maintain our humanity throughout the research process, it is largely impossible to escape the subjective experience, even for the most seasoned of researchers. As we proceed through the research process, our humanness informs us and often directs us through such subtleties as intuition or 'aha' moments. Speaking about the world of human experience requires an extensive commitment in terms of time and dedication to process; however, this world is often dismissed as 'subjective' and regarded with suspicion. This paper acknowledges that small qualitative studies are not generalizable in the traditional sense, yet have redeeming qualities that set them above that requirement.

VOLUME AND HIPPOCAMPAL FUNCTION IN MEDIAL TEMPORAL LOBE EPILEPSY

Introduction: The functional Magnetic Resonance (fMRI) is important in the evaluation of language and memory of patients with temporal lobe epilepsy. The fMRI has also enabled to observe how the structures in the medial temporal cortex have functional laterality according to the dominance of language, with a hemisphere which is specialized in the expressive and receptive aspects of language and the encoding of verbal material. Objective: To relate the left hippocampus integrity with the degree of asymmetry of the language dominance seen by fMRI. Materials and methods: Images with T1 volumetric information and EPI with T2 information are obtained using a 1.5T magnetic resonator, during the execution of complex scenes encoding paradigms, as well as during the generation of words and a semantic decision in a set of 12 control subjects and different patients who are potential candidates for epilepsy surgery. Results: The automatized volumetric properties of the control group hippocampus do not show significant asymmetry. Indifferent patients with hippocampal sclerosis, numerical indexes are obtained, which are in accordance with the implication of the integrity of the left hippocampus with the asymmetry indexes in the language paradigms. Conclusions: Among the results of the implementation of the memory and language protocol, using fMRI for patients with temporal lobe epilepsy, one can emphasize the evidences obtained using fMRI regarding the implications of the left hippocampus in the language network and the effects of its dysfunction in the migration patterns of language towards the contralateral hemisphere.

Longitudinal changes and predictors of adolescents’ enjoyment in physical education

Longitudinal studies on adolescents’ enjoyment in physical education (PE) are lacking. This study examined students’ self-reported enjoyment and predictors of enjoyment in PE in school among students from age 14 to 19, using questionnaires and interviews. From the results, enjoyment in PE increases among girls during high school, while students that participate weekly in organized sport report greater enjoyment in PE than those who are not, at the age of 14; but there is no such group difference in high school. Furthermore, the findings from the interview analysis highlight the importance of greater autonomy in high school. Key words: Enjoyment, physical education, adolescents, student characteristics.
A review of the relationships between personality and performance in small groups.

A wide range of practical and theoretical interests have found expression in the study of small groups. As the major bibliographic sources (Hare, Borgatta, & Bales, 1955; McGrath, 1957; Strodtbeck & Hare, 1957) amply attest, small group research has proceeded along numerous independent lines. One interest, however, has been dominant for more than 50 years. While phrased in various ways, the relationship between the personality characteristics of the individual and his performance in the group has remained a central concern. There have been at least three conceptual approaches to this problem. One approach considers the individual as having various needs and as being motivated to satisfy some of these needs through interaction with others; the point of interest is the relation between the individual's personality and his goal-directed behavior in groups. In another view, the individual is conceived of as a stimulus, or set of stimuli, for the other members of the group, and the
ImproVing Diffusin-g-s-DUct_Pefformance

Pr,! = The objective of this research was to study ways to P0 -- reduce inlet flow distortion (Le., total pressure nonunifor- p--.ff = mity) and improve total pressure recovery in a diffusing po,,,y = S-duet. This was accomplished by controlling the development of secondary flows within the duct through the = use of tapered-fin type vortex generators. Reported herein are results for the bare duct and seven different config-r = urations of vortex generators. Data presented for each R = configuration include surface static pressure, surface flow visualization, and exit plane total pressure and transverse Reo_ = velocity. The performance of each configuration was as-s = sessed by calculating total pressure recovery and inlet distortion descriptors from the data and comparing them 0 ffi to the values for the bare duel The best configuration _ = tested reduced distortion (as _ured by the DC(45) and De(90) descriptors) by more than 50% while improving total pressure recovery by 0.5%. These results should provide valuable guidance in designing vortex generator imtallatiom in ducts and for assessing the accuracy of CFD methods to calculate duct flows with imtalled vortex generators.
TESTING FOR PPP USING SADC REAL EXCHANGE RATES

This paper attempts to provide evidence indicating that the Purchasing Power Parity (PPP) puzzle is becoming less of a puzzle. It present the results of Augmented Dickey-Fuller (ADF) test, nonlinear tests of nonstationarity, and Bayesian unit root tests, applied to ten SADC countries. The Bayesian tests were found to be biased in favour of a trend stationary model in all cases. It is argued that nonlinear approaches to exchange rate adjustments are likely to provide a firmer basis for inference and stronger support for the PPP in the long-term. This is more so at 1 per cent and 5 per cent levels of significance.
SimBoost: A Read-Across Approach for Drug-Target Interaction Prediction Using Gradient Boosting Machines

Computational prediction of the interaction between drugs and targets is a standing challenge in drug discovery. High performance on binary drug-target benchmark datasets was reported for a number of methods. A possible drawback of binary data is that missing values and non-interacting drug-target pairs are not differentiated. In this paper, we present a method called SimBoost that predicts the continuous binding affinities of drugs and targets and thus incorporates the whole interaction spectrum from true negative to true positive interactions in the learning phase. Additionally, we propose a version called SimBoostQuant which computes a prediction interval in order to assess the confidence of the predicted affinity. We evaluate SimBoost and SimBoostQuant on three continuous drug-target datasets and show that our methods outperform the state-of-the-art models.
Premature Rupture Of Membranes At Week 19: Favorable Pregnancy Outcome And Four Years Follow-Up After Expectant Management

Premature rupture of membrane (PROM) and preterm birth are the major public health problems accounting for mortality and morbidity both in infant and mother. Although, there are some reports available in world literature on PROM at week 20 and early preterm births prior to week 34, but most of these cases end in catastrophic outcome. In the present study a case report on PROM, associated with persistently marked oligohydramnios at week 19 is presented and discussed. The patient was managed expectantly and delivered at week 35 without any complication. Four years follow-up in pediatric clinics revealed a healthy normal child. Even though, the PROM was not anticipated – but its timely detection, prompt laboratory investigations, scrupulous patient care and meticulous management of infections, illness and hyperbilirubinemia lead to a favorable outcome. Subsequent care of the baby in the Neonatal Intensive Care Unit (NICU) and good oral feeding from day 1 appears to influence the normal progress of the baby.
RADIOLOGY OF FRACTURES – CLASSIFICATION, HEALING, COMPLICATIONS

In direct fracture healing no or just a minimal amount of external callus is formed. The strain in the fracture gap is low enough to allow direct bone formation. This can only occur in anatomically reconstructed fractures that are rigidly stabilized. In indirect fracture healing, new bone is formed by transformation of fibrous tissue or cartilaginous tissue (endochondral bone formation). This occurs when the circumstances are not conducive to immediate ingrowth of bone (for instance: high strain, movement, less vascularization or if the defect is too wide).
Pom-pom-like constitutive equations for comb polymers

In analogy with the pom-pom model, we introduce a simple model for comb polymers with multiple side-arms attached to a linear backbone by considering a set of coupled equations describing the stretch in the individual interbranch backbone segments. The stretch equations predict a sudden onset of backbone stretch as the flow rate is increased. Drag-strain coupling smooths this transition to some extent. For a series of well characterized polyisoprene and polystyrene combs, we find good agreement with the experimentally determined transient stress growth coefficients in uniaxial extension.
Transplantation of human pluripotent stem cells overexpressing ERRγ can efficiently improve the symptoms of type 2 diabetes patient

In 1922, Banting et al.,1 first discovered that daily insulin injection could decrease the blood glucose levels and other associated symptoms of type I diabetes, and since then, insulin is generally used for treatment of diabetes with absolute insulin deficiency.1,2 However, with the progressing of the symptoms, exogenous insulin administration need to be intensified with more and more dosages, and even worse, the only administration of insulin cannot maintain blood glucose levels within the narrow physiological range that protects from development of various diabetic complications.2 In addition, currently available therapies for diabetes have limited effects in preventing the progression of diabetes complications and repairing existing tissue damages.3 Therefore, more efficient strategies for diabetes treatment are urgently needed to develop.
Do Holarctic ant species exist? Trans‐Beringian dispersal and homoplasy in the Formicidae

Continents harbour unique faunas, and only a small percentage of species naturally inhabit more than a single continent. This pattern is most evident in the insects, a morphologically small and extremely diverse group. Nevertheless, 12 species of ants have traditionally been recognized as native to both North America and Eurasia, the Holarctic region. Since intercontinental dispersal is presumably rare in ants, allopatric speciation in the absence of gene flow can be expected over evolutionary time. Here, we reassess the existence of Holarctic ant species and reconstruct their biogeographical history.
Consumption of Pomegranate Juice Attenuates Exercise-Induced Oxidative Stress, Blood Pressure and Urinary Cortisol/Cortisone Ratio in Human Adults

Oxidative stress is exacerbated in overweight and obese individuals after acute exercise compared with their non-obese counterparts. Antioxidant supplementation of the diet may be one intervention to reduce exercise-induced oxidative stress in this vulnerable population. The aim of this study was to investigate whether polyphenol-rich pomegranate juice attenuates post-exercise oxidative stress and contributors to oxidative stress (glucocorticoids) and blood pressure in healthy overweight subjects. Healthy male and female subjects participated in a randomized placebo controlled parallel pilot-study (mean BMI: 26.7 ± 6.6 kg/m2). Two groups of participants (n=12) received either 500 ml/day of pomegranate juice (containing 1685 mg GAE) or placebo (matched for total energy). Participants completed two standardized 30 min treadmill tests (50% Wmax) at baseline and after one week of the intervention. Exercise-induced lipid peroxidation (MDA) was significantly lower following pomegranate juice consumption compared with placebo (31.2 ± 10.6 to 26.5 ± 9.8 MDA μmole/day) (p=0.035). Urinary free cortisol was reduced from 179.4 ± 53.2 to 125.6 ± 43.5 nmole/24h which was significant (p=0.042). In addition, there was an increase in urinary free cortisone from 112.2 ± 40.4 to 187.6 ± 90.2 nmole/24 h (p=0.045), and a significant decrease in the urinary free cortisol/cortisone ratio (p=0.009) from 1.6 ± 1.1 to 0.67 ± 0.55 following one week of pomegranate juice intake. Pomegranate juice consumption was also found to decrease systolic blood pressure pre-exercise (136.7 ± 11.7 to 131.8 ± 8.8 mmHg (p=0.007), and post-exercise from 158.8 ± 15.8 to 148.1 ± 12.3 mmHg (p<0.01) and diastolic blood pressure (86.3 ± 10.6 to 82.5 ± 6.8 mmHg (p=0.04) and 103.1 ± 12.5 to 93.9 ± 11.5 mmHg (p=0.001), pre and post exercise, respectively. Correlation between the change in cortisol/cortisone ratio with the effect on blood pressure showed a negative significant association post pomegranate juice intake (p=0.028 for systolic and p=0.008 for diastolic BP). There were no changes in lipid peroxidation or blood pressure following placebo treatment. In conclusion, these findings suggest that pomegranate juice consumption prior to an acute bout of moderate intensity exercise may help to alleviate exercise-induced oxidative stress, and lower blood pressure in the overweight and obese population.
CHOP Chemotherapy plus Rituximab Compared with CHOP Alone in Elderly Patients with Diffuse Large-B-Cell Lymphoma

Background The standard treatment for patients with diffuse large-B-cell lymphoma is cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP). Rituximab, a chimeric monoclonal antibody against the CD20 B-cell antigen, has therapeutic activity in diffuse large-B-cell lymphoma. We conducted a randomized trial to compare CHOP chemotherapy plus rituximab with CHOP alone in elderly patients with diffuse large-B-cell lymphoma. Methods Previously untreated patients with diffuse large-B-cell lymphoma, 60 to 80 years old, were randomly assigned to receive either eight cycles of CHOP every three weeks (197 patients) or eight cycles of CHOP plus rituximab given on day 1 of each cycle (202 patients). Results The rate of complete response was significantly higher in the group that received CHOP plus rituximab than in the group that received CHOP alone (76 percent vs. 63 percent, P=0.005). With a median follow-up of two years, event-free and overall survival times were significantly higher in the CHOP-plus-rit.

Temporal perception of acoustically presented time series

Data from three experiments on serial perception of temporal intervals are reported. Sequences of short acoustic signals (‘pips’) separated by periods of silence were presented to the observers (N = 24, 16, 12). The inter-pip intervals were generated to form geometric or alternating se- ries, while the modulus 1 + δ of the stimulus series and the base duration T 0 (in the range from 1.1 to 6 seconds) were varied as independent parameters. The observers had to judge whether the pips sequences were accelerating, decelerating, or uniform, or to distinguish regular from irregular sequences. ‘Intervals of subjective uniformity’ ( ISU ) were obtained by fitting Gaus- sian psychometric functions to individual subjects’ responses. Progression towards longer base durations (T 0 = 4 . 4 or 6 seconds) shifts the ISU s towards negative δ s, i. e. , accelerating series. This finding is compatible with the phenomenon of ‘subjective shortening’ of past temporal intervals, accounted for by the lossy integration model of internal time representation.
