Studies on Glass Powder as Partial Replacement of Cement in Concrete Production

Cement manufacturing industry is one of the carbon dioxide emitting sources besides deforestation and burning of fossil fuels. The global warming is caused by the emission of green house gases, such as CO2, to the atmosphere. Among the greenhouse gases,CO2 contributes about 65% of global warming. The global cement industry contributes about 7% of greenhouse gas emission to the earth’s atmosphere. In order to address environmental effects associated with cement manufacturing, there is a need to develop alternative binders to make concrete. Consequently extensive research is on going into the use of cement replacements, using many waste materials and industrial by products. Efforts have been made in the concrete industry to use waste glass as partial replacement of coarse or fine aggregates and cement. In this study, finely powdered waste glasses are used as a partial replacement of cement in concrete and compared it with conventional concrete. This work examines the possibility of using Glass powder as a partial replacement of cement for new concrete. Glass powder was partially replaced as 10%, 20%, 30% and 40% and tested for its compressive, Tensile and flexural strength up to 60 days of age and were compared with those of conventional concrete; from the results obtained , it is found that glass powder can be used as cement replacement material upto particle size less than 75μm to prevent alkali silica reaction.
Automating the Application of Design Patterns

Design patterns today form a principal heuristic of OOD and are widely used in numerous application domains. However, lack of suitable formalisms prevents the automation of the technical aspects in their implementation. We present an approach of rigorous specification of design patterns and a prototype of a tool that automates most of their application. This tool is also capable of enforcing design principles that can be expressed in terms of constructs and relations in an OOPL. Design patterns are a fundamental object oriented design heuristic. Today, they form the most important means of delivering knowledge and experience from the expert to the novice, from the veteran to the recruit. A description of the design patterns of a well-designed class library is the most efficient method of abstracting its description and delivering its essentials, leaving out the numerous dispensable detail that may not contribute to the design of future libraries. For these reasons a great deal of research is conducted in the attempt to discover and describe design patterns. The readers that are not familiar with design patterns can use [Gamma et. al 95] and [Coplien 94] as introductions to the topic. There are three types of activities in the research of design patterns: 1. The “discovery” or invention of new patterns 2. The classification and description of design patterns 3. and application of design patterns This distinction reassures the observation of the practice of design patterns is both science and art. It is art in the sense that scientific discovery is art, much in accordance to the oldfashioned philosophical concept of “context of discovery”. As a result, the detection or “invention” of design patterns are activities that cannot be reduced to a small set of logical deductions by today’s means. For the same reason their “automation”, if possible at all, requires techniques that appear to belong to the realm of artificial intelligence (AI) or knowledge-based reasoning. Nonetheless, the more “scientific” aspects of this practice numbered 2 and 3 in our list appear to be good candidates for automation, or so we claim. The manual application of many simple patterns (such as the Prototype and Observer design patterns described in [Gamma et. 1 The Department of Computer Science, School of Mathematics, Tel Aviv University, Tel Aviv, Israel. 2 The Faculty of Computer Science, The Israeli Technion, Haifa, Israel.
Neuromuscular fatigue during 200 m breaststroke.

THE AIMS OF THIS STUDY WERE i) to analyze activation patterns of four upper limb muscles (duration of the active and non-active phase) in each lap of 200m breaststroke, ii) quantify neuromuscular fatigue, with kinematics and physiologic assessment. Surface electromyogram was collected for the biceps brachii, deltoid anterior, pectoralis major and triceps brachii of nine male swimmers performing a maximal 200m breaststroke trial. Swimming speed, SL, SR, SI decreased from the 1(st) to the 3(rd) lap. SR increased on the 4(th) lap (35.91 ± 2.99 stroke·min(-1)). Peak blood lactate was 13.02 ± 1.72 mmol·l(-1) three minutes after the maximal trial. The EMG average rectified value (ARV) increased at the end of the race for all selected muscles, but the deltoid anterior and pectoralis major in the 1(st) lap and for biceps brachii, deltoid anterior and triceps brachii in the 4(th) lap. The mean frequency of the power spectral density (MNF) decreased at the 4(th) lap for all muscles. These findings suggest the occurrence of fatigue at the beginning of the 2(nd) lap in the 200m breaststroke trial, characterized by changes in kinematic parameters and selective changes in upper limb muscle action. There was a trend towards a non-linear fatigue state. Key PointsFatigue in the upper limbs occurs in different way as it described by 100m swimming events.Neuromuscular fatigue was estimated by analyzing the physiological changes (high blood lactate concentrations), biomechanical changes in the swimming stroke characteristics (decreased in swimming velocity), and by the changes in the EMG amplitude and frequency parameters at the end of the swimming bout.The amplitude signal of EMG provided by the ARV demonstrated an increase at the end with the respect to the beginning for all muscles under study, excepted for the muscle deltoid anterior.The mean frequency (MNF) in our study decrease at the end of the swimming in the 4(th) lap relative to the 1(st) lap for all muscles under observation, along the 200m breaststroke.
Persistence of mild to moderate atopic dermatitis.

IMPORTANCE Atopic dermatitis (AD) is a common illness of childhood. OBJECTIVE To evaluate the natural history of AD and determine the persistence of symptoms over time. DESIGN, SETTING, AND PARTICIPANTS A cross-sectional and cohort study of a nation-wide long-term registry of children with AD enrolled in the Pediatric Eczema Elective Registry (PEER). MAIN OUTCOMES AND MEASURES Self-reported outcome of whether a child's skin was AD symptom-free for 6 months at 6-month intervals. RESULTS A total of 7157 patients were enrolled in the PEER study for a total of 22,550 person-years. At least 2 years of follow-up were observed for 4248 children and at least 5 years of follow-up were observed for 2416 children. Multiple demographic and exposure variables were associated with more persistent AD. At every age (ie, 2-26 years), more than 80% of PEER participants had symptoms of AD and/or were using medication to treat their AD. It was not until age 20 years that 50% of patients had at least 1 lifetime 6-month symptom- and treatment-free period. CONCLUSIONS AND RELEVANCE Based on this large longitudinal cohort study, symptoms associated with AD seem to persist well into the second decade of a child's life and likely longer. Atopic dermatitis is probably a life-long illness.
Reverse Circle Cipher for personal and network security

Many data encryption techniques have been employed to ensure both personal data security and network security. But few have been successful in merging both under one roof. The block cipher techniques commonly used for personal security such as DES and AES run multiple passes over each block making them ineffective for real time data transfer. Also, ciphers for network security such as Diffie-Hellman and RSA require large number of bits. This paper suggests a simple block cipher scheme to effectively reduce both time and space complexities and still provide adequate security for both security domains. The proposed Reverse Circle Cipher uses `circular substitution' and `reversal transposition' to exploit the benefits of both confusion and diffusion. This scheme uses an arbitrarily variable key length which may even be equal to the length of the plaintext or as small as a few bits coupled with an arbitrary reversal factor. This method of encryption can be utilized within stand alone systems for personal data security or even streamed into real time packet transfer for network security. This paper also analyses the effectiveness of the algorithm with respect to the size of the plaintext and frequency distribution within the ciphertext.
Domain-independent automatic keyphrase indexing with small training sets

Keyphrases are widely used in both physical and digital libraries as a brief but precise summary of documents. They help organize material based on content, provide thematic access, represent search results, and assist with navigation. Manual assignment is expensive, because trained human indexers must reach an understanding of the document and select appropriate descriptors according to defined cataloguing rules. We propose a new method that enhances automatic keyphrase extraction by using semantic information about terms and phrases gleaned from a domain-specific thesaurus. The key advantage of the new approach is that it performs well with very little training data. We evaluate it on a large set of manually indexed documents in the domain of agriculture, compare its consistency with a group of six professional indexers, and explore its performance on smaller collections of documents in other domains and of French and Spanish documents.
Data’s Hidden Data: Qualitative Revelations of Sports Efficiency Analysis brought by Neural Network Performance Metrics

In the study of effectiveness and efficiency of an athlete’s performance, intelligent systems can be applied on qualitative approaches and their performance metrics provide useful information on not just the quality of the data, but also reveal issues about the observational criteria and data collection context itself. 2000 executions of two similar exercises, with different levels of complexity, were collected through a single inertial sensor applied on the fencer’s weapon hand. After the signals were split into their key segments through Dynamic Time Warping, the extracted features and respective qualitative evaluations were fed into a Neural Network to learn the patterns that distinguish a good from a bad execution. The performance analysis of the resulting models returned a prediction accuracy of 76.6% and 72.7% for each exercise, but other metrics pointed to the data suffering from high bias. This points towards an imbalance in the qualitative criteria representation of the bad executions, which can be explained by: i) reduced number of samples; ii) ambiguity in the definition of the observation criteria; iii) a single sensor being unable to fully capture the context without taking the actions of the other key body segments into account.
The Behavioural and Neural Correlates of Social Cognition: A Dimensional Approach in Youth with Mental Illness

Heterogeneity in social cognitive performance and social function is a major obstacle in the identification of consistent biomarkers of impairment for schizophrenia spectrum disorders (SSD), autism spectrum disorders (ASD), and bipolar disorder (BD). Improved etiological subtyping and a better understanding of mediating mechanisms in neural circuits could facilitate targeted treatment development based on underlying pathology. This thesis explores the usefulness of Similarity Network Fusion (SNF), a transdiagnostic and data-driven clustering approach, in uncovering more neurobiologically homogenous groups of individuals with social cognitive impairments. The integration of multi-modal neuroimaging, social cognitive, neurocognitive, and demographic data reveal four distinct groups of participants across SSD, ASD, BD, and healthy youth with differing neuroanatomical profiles in key nodes of the frontoparietal and cortical midline circuits. Our findings suggest that structural neural circuit deficits may help explain poor social cognitive performance in SSD, ASD, and BD.
Young people’s investments in sexual relationships: A different prioritization of self in the negotiation of safe sex practices in South Africa

In the South African context of high HIV prevalence, sexual relationships are entwined with risk. This qualitative study in a rural context examined how young people negotiate sexual practices and engage with this risk. Data was gathered from men and women (aged 15 to 33) in eight focus groups and 11 individual interviews. Abdication of self-care and deprioritization of self in the negotiation of safe sexual practices are reformulated into an understanding of the varied investments that young people make in particular kinds of sexual relationships. Sexual activity was found to underpin social reputation and identity production. In the trade-off between health protection and group membership, identity was related to investments in relationships that secured status for both genders. Future health-related interventions would need to work with other constructions of self in sexual relationships.
Assessment and evaluation of symptomatic steroid-naive asthmatics without sputum eosinophilia and their response to inhaled corticosteroids

Eosinophilic airway inflammation is one of the hallmarks of asthma. Sputum eosinophilia has been suggested as a predictor of the response to inhaled corticosteroids in asthma. This study sought to investigate the proportion of steroid-naive uncontrolled asthmatics without significant sputum eosinophilia (≤1%) and to examine whether sputum eosinophilia could predict the response to inhaled corticosteroids. A total of 51 mild uncontrolled steroid-naive asthmatics who had not been treated with oral or inhaled corticosteroids for at least 3 months were investigated. The evaluation included a spirometry, methacholine inhalation challenge and sputum induction on two occasions, one at baseline and the other after 1 month of treatment with 250 µg twice-daily fluticasone propionate. Of the 51 subjects, 15 had an eosinophil count ≤1%, and 46 completed the two visits. Patients with baseline sputum eosinophils ≤1% (n=14) were compared with those with sputum eosinophils >1% (n=32). The baseline characteristics of these two groups were similar. After 1 month of treatment, respiratory symptoms, quality of life, forced expiratory volume in one second (FEV1) and provocative concentration causing a 20% fall in FEV1 improved in both groups. The absence of sputum eosinophilia does not seem to be an indicator of poor response to inhaled corticosteroid treatment in steroid-naive asthmatics. However, this finding needs to be investigated further in a double-blind, placebo-controlled study, entirely designed to answer this question.
Histoarchitecture of the Ovary of Rhipicephalus (Boophilus) annulatus during Pre- and Postengorgement Period

The present communication describes the detailed day wise study of histological changes of the ovary of Rhipicephalus (Boophilus) annulatus in the postengorgement period together with the systematic classification of their oocytes. The ovary of R. (B.) annulatus is panoistic type with an asynchronous development of oocytes. All the stages (II, III, IV, and V) of oocytes except stage I were similar to R. (B.) microplus. The stage I oocytes showed basophilia, which was not reported earlier in other species of ticks. Day wise changes were in the form of presence of oogonia in partially fed and day one engorged adults, considerable degeneration of oocytes on day two, emergence of new wave of oocytes on day three, presence of mature oocytes up to day eight, and complete degeneration of ovarian tissue from day eight onwards. The degenerative changes in the ovary appeared initially in the oocytes followed by germinal epithelium.
Effects of Propofol on Epileptiform Activity and Hippocampal Morphology inFebrile Convulsions and Pilocarpine Induced Seizures

Abstract Epidemiological and recent prospective analyses of long Febrile Seizures (FS) support the idea that such seizures can provoke Temporal Lobe Epilepsy (TLE) in some children. Because of the high prevalence of these seizures, if epilepsy was to arise as their direct consequence, this would constitute a significant clinical problem. Animal studies have revealed that exposure of hippocampal neurons to FS early in life, particularly prolonged or frequently repetitive FS, or together with brain malformation, may lead to sustained dysfunction of these cells including long-term memory impairment or epileptogenesis, in spite of the absence of neuronal damage. We established a hyperthermia model of febrile convulsions in young adult rats, and studied the effects of propofol treatment general anesthetic acting via GABA-A receptor on epileptiform activity and the morphological features of medial temporal lobe. We found statistically significant neuronal losses in the CA1, CA3 and dentate gyrus regions of hyperthermiaapplied rats as compared to the control rats. We also observed that propofol administration suppressed epileptic discharges in EEG and prevented clinical seizures behaviors. It took a median of 11 (range, 6-40) minutes for propofol to stop seizures. We conclude that prevention of epilepsy-related damage can be achieved via epileptogenesis-based clinical approaches, and that propofol is an effective agent in the hyperthermia-induced status epilepticus model.
Memory performance model for loops and kernels on Power3 processors

Summary form only given. A performance model for loops and kernels limited by memory access is developed that is applicable to Power3 processors. The output of the model is the time delay arising from cache and TLB misses. The input variables are the miss rates of each cache and the TLB, while the model parameters are the miss penalties of each cache and the TLB. Load misses are treated separately from store misses and typically have smaller penalties because of prefetching. The parameters have been obtained by fits to data from simple test loops measured with a hardware performance monitor. Results are presented for two types of Power3 processor running in serial as well as for one of the processor types running in parallel. For codes limited by store misses, the model fits the data very well. For codes limited by load misses, the model shows greater variability relative to the data, presumably because of the limited treatment of prefetching.

Curiosity and social interpretative schemas: their role in cognitive development.

Introduction Children can copy what others do, and they are ready to learn from others through imitation as early as around the end of their first year (Barr, Dowden, & Hayne, 1996; Killen & Uzgiris, 1981). Based on recent comparative analyses of social learning, it has been argued that the term imitation should be applied only to cases in which infants understand the goal of the model’s actions, copy the specific actions used by the model, and reproduce the modeled result (Tomasello, 1999; Want & Harris, 2001). Imitation can be contrasted with emulation, where children understand the goal of the model’s actions and reproduce the modeled result but do not copy the specific means used by the model. It had been argued previously that most of the time infants imitate others’ actions (rather than performing 0022-0965/$ see front matter 2008 Elsevier Inc.

The Role of Clouds in the Tropospheric NOx Cycle: A New Modeling Approach for Cloud Chemistry and Its Global Implications

We present a new method for simulating heterogeneous (surface and multiphase) cloud chemistry in atmospheric models that do not spatially resolve clouds. The method accounts for cloud entrainment within the chemical rate expression, making it more accurate and stable than other approaches. Using this “entrainment‐limited uptake,” we evaluate the role of clouds in the tropospheric NOx cycle. Past literature suggests that on large scales, losses of N2O5 and NO3 in clouds are much less important than losses on aerosols. We find, however, that cloud reactions provide 25% of tropospheric NOx loss in high latitudes and 5% of global loss. Homogeneous, gas phase hydrolysis of N2O5 is likely 2% or less of global NOx loss. Both clouds and aerosols have similar impacts on global tropospheric O3 and OH levels, around 2% each. Accounting for cloud uptake reduces the sensitivity of atmospheric chemistry to aerosol surface area and uptake coefficient since clouds and aerosols compete for the same NO3 and N2O5.
Outlier Robust Online Learning

We consider the problem of learning from noisy data in practical settings where the size of data is too large to store on a single machine. More challenging, the data coming from the wild may contain malicious outliers. To address the scalability and robustness issues, we present an online robust learning (ORL) approach. ORL is simple to implement and has provable robustness guarantee -- in stark contrast to existing online learning approaches that are generally fragile to outliers. We specialize the ORL approach for two concrete cases: online robust principal component analysis and online linear regression. We demonstrate the efficiency and robustness advantages of ORL through comprehensive simulations and predicting image tags on a large-scale data set. We also discuss extension of the ORL to distributed learning and provide experimental evaluations.
