Effect of Sugarcane Bagasse Ash on the Engineering Properties of Blended Sandcrete Blocks

This research investigates the effect of Sugarcane Bagasse Ash (SBA) on the engineering properties of sandcrete blocks produced with optimal amount of blended lateritic and marine sand. Sandcrete hollow blocks (450mm x 225mm x 225mm) were made by blending varying contents of marine sand and lateritic sand using the nominal mix ratio of 1:6 (cement: sand). Marine and clean lateritic sand were blended at intervals of 10%. A total of 90 sandcrete blocks were casted and the compressive strengths of the blocks determined at 7, 14 and 28 days. The 28 day compressive strength of mixes containing 0, 10, 20, 30, 40, 50, 60, 80 and 100% marine sand were, 4 . 47, 5.10, 5.25, 5.33, 5.20, 4.63, 4.58, 3.88 and 3.76 N/mm respectively. The 28 days strength for both blends of sand exceeded the minimum strength value of 3.45N/mm specified by BS 6073:2.Sandcrete blocks made with 30:70 marine-lateritic sand blending ratio produced the highest compressive strength. Using this ratio, 90 sandcrete blocks were casted by replacing cement with Sugar Bagasse Ash in the ratio of 0%, 5%, 10% 15% 20% and 25% by weight. The blocks were tested for compressive strength, density, water absorption and durability. The 28 day compressive strength were 5.33, 5.29, 5.18, 4.71, 3.42, 3.08 N/mm for 0, 5, 10, 15, 20 and 25 % replacement respectively. Upto 15% replacement levels met the minimum compressive strength recommended in standards. The results for water absorption, density and durability of the blocks were within the acceptable limits. Key Words--Sugarcane Bagasse Ash, Sandcrete blocks, Lateritic Sand, Marine Sand, Blended Sand, Compressive Strength, water absorption, durability.

Setor de Suínos, Faculdade de Veterinária, Universidade Federal do Rio Grande do Sul, Av. Bento Gonçalves 9090, Porto Alegre, RS 91540-000, Brazil. E-mail: davidbarcellos@terra.com. br A case-control study was carried out in litters of 1 to 7-day-old piglets to identify the main infectious agents involved with neonatal diarrhea in pigs. Fecal samples (n=276) from piglets were collected on pig farms in the State of Rio Grande do Sul, Brazil, from May to September 2007. Litters with diarrhea were considered cases (n=129) and normal litters (n=147) controls. The samples were examined by latex agglutination test, PAGE, conventional isolating techniques, ELISA, PCR, and microscopic methods in order to detect rotavirus, bacterial pathogens (Escherichia coli, Clostridium perfringens type A and C, and Clostridium difficile), and parasites (Coccidian and Cryptosporidium spp.). Outbreaks of diarrhea were not observed during sampling. At least one agent was detected in fecal samples on 25 out of 28 farms (89.3%) and in 16 farms (57.1%) more than one agent was found. The main agents diagnosed were Coccidia (42.86%) and rotavirus (39.29%). The main agents identified in litters with diarrhea were Clostridium difficile (10.6%), Clostridium perfringens type A (8.8%) and rotavirus (7.5%); in control litters, Clostridium difficile (16.6%) and Coccidian (8.5%). Beta hemolytic Escherichia coli and Clostridium perfringens type C were not detected. When compared with controls, no agent was significantly associated with diarrhea in case litters. These findings stress the need for caution in the interpretation of laboratorial diagnosis of mild diarrhea in neonatal pigs, as the sole detection of an agent does not necessarily indicate that it is the cause of the problem.
5-2014 ZEBRA : Zero-Effort Bilateral Recurring Authentication

Common authentication methods based on passwords, tokens, or fingerprints perform one-time authentication and rely on users to log out from the computer terminal when they leave. Users often do not log out, however, which is a security risk. The most common solution, inactivity timeouts, inevitably fail security (too long a timeout) or usability (too short a timeout) goals. One solution is to authenticate users continuously while they are using the terminal and automatically log them out when they leave. Several solutions are based on user proximity, but these are not sufficient: they only confirm whether the user is nearby but not whether the user is actually using the terminal. Proposed solutions based on behavioral biometric authentication (e.g., keystroke dynamics) may not be reliable, as a recent study suggests. To address this problem we propose Zero-Effort Bilateral Recurring Authentication (ZEBRA). In ZEBRA, a user wears a bracelet (with a built-in accelerometer, gyroscope, and radio) on her dominant wrist. When the user interacts with a computer terminal, the bracelet records the wrist movement, processes it, and sends it to the terminal. The terminal compares the wrist movement with the inputs it receives from the user (via keyboard and mouse), and confirms the continued presence of the user only if they correlate. Because the bracelet is on the same hand that provides inputs to the terminal, the accelerometer and gyroscope data and input events received by the terminal should correlate because their source is the same – the user’s hand movement. In our experiments ZEBRA performed continuous authentication with 85% accuracy in verifying the correct user and identified all adversaries within 11 s. For a different threshold that trades security for usability, ZEBRA correctly verified 90% of users and identified all adversaries within 50 s.
Emissions of trace gases and aerosols from wildfires in Portugal in summer 2009-Experimental results from ground base measurements

In summer 2009, emissions of trace gases and aeroso ls from several wildfires registered in Portugal were sampled. A portable high-volume sampl er was used to collect sequentially, on quartz fibre filters, coarse (PM 2.5-10) and fine (PM2.5) smoke particles. Tedlar air sampling bags have been used for complementary chemical character isation of the gaseous phase. Total hydrocarbons and carbon oxides (CO 2 and CO) were measured using automatic analysers wi th flame ionisation and non-dispersive infrared detect ors, respectively. The carbonaceous content (elemental and organic carbon, EC/OC) of particulat e matter was analysed by a thermal-optical transmission technique. Emission factors of species that are favoured by the smouldering phase (e.g. CO) were above the values reported in the lit erature for biomass burning in other ecosystems. Emission factors for CO were 231±117 g kg -1 biomass (dry basis) burned. Compounds whose emissions are promoted in fresh plumes and during t he flaming burning phase, such as CO 2, produced emission factors generally lower than thos e proposed for savannah and tropical forest fires. The emission factors for CO 2 were in the range from about 1000 to 1700 g kg . Total hydrocarbons, PM2.5, PM10 and OC presented variable emissions, but in genera l substantially higher than values reported for wildfires in Africa n nd Amazonian biomes. The emission factors obtained in Portugal were as follows (in g kg -1 biomass, dry basis): 6-350 for total hydrocarbons, 0.5-42 for PM2.5, 1-60 for PM10, and 0.2-42 for OC (in PM 10). The organic carbon-to-elemental carbon ratios measured in the present study largely exceed those obtained by other researchers.
DoF-based Classification of Augmented Reality Applications

In recent years Augmented Reality (AR) has become more and more popular, especially since the availability of mobile devices, such as smartphones or tablets, brought AR into our everyday life. Although the AR community has not yet agreed on a formal definition of AR, some work focused on proposing classifications of existing AR methods or applications. Such applications cover a wide variety of technologies, devices and goals, consequently existing taxonomies rely on multiple classification criteria that try to take into account AR applications diversity. In this paper we review existing taxonomies of augmented reality applications and we propose our own, which is based on (1) the number of degrees of freedom required by the tracking of the application, as well as on (2) the visualization mode used, (3) the type of tracking used in the application and (4) the rendering modalities used in the application. Our taxonomy covers location-based services as well as more traditional vision-based AR applications. Although AR is mainly based on the visual sense, other rendering modalities are also covered by the same degree-of-freedom criterion in our classification. This article is mainly based on our previous paper published in the 3rd ACM Augmented Human AH’12 conference [29].
The Methods of Statutory Interpretation in the Practice of the High Courts of Hungary 1

It is a cliché in the jurisprudence that written legal norms perpetually need to be interpreted due to the medium through which the language is able to manifest itself being always vague and ambiguous� Therefore, however much a statute be precisely prepared and drafted, such situations inevitably occur when one cannot decide whether or not a norm in hand concerns a given statement of facts and if they can then what is its ‘real’ tenor1� Exactly for this reason, legal provisions always need to be interpreted before application, that is, that the most adequate meaning has to be revealed relevant to the hermeneutic situation in question�
The Routledge Handbook of Semantics

the reason for this is that every transfer of possession can be conceptualized as an abstract movement event in the dimension of possession spaces: When Ann gives Beth a car, then the car is moved from the possession of Ann into the possession of Beth. Under closer scrutiny, one is not obliged to resort to “possession spaces” to explain that many verbs occur in both constructions. As mentioned in section 1 above, verbs of transfer of possession often imply two simultaneous events, a change of possession and a change of location. The DO-construction highlights the change of possession, the PO-construction the locational change (see Koenig and Davis (2006) where verbs are represented by a set of elementary predicates, one of them being highlighted as the KEY). A change of possession is conceptualized as instantaneous, so the DO-construction is odd when a path is presupposed (see Jackendoff (1990)). This nicely explains the oddity of halfway in (9b). A general problem for Krifka’s semantic distinction between the possessive and the loca-tive reading and his strict mapping assumption is that they only hold as a tendency. In their corpus-based analysis, Bresnan and Nikitina (2003) showed that the examples assumed to be ungrammatical in the pertinent literature do occur, though admittedly only in the much larger corpus of web documents. They appear not to be grammatically impossible, but just improbable. Here we only show two counterexamples to Krifka’s assumptions. Cf.

Artigo Técnico A Simple Kit of Plate-Trapped Antigen Enzyme-Linked Immunosorbent Assay for Identification of Plant Viruses 1 Um Simples Kit de “ Enzyme-Linked Immunosorbent Assay ” para Identificação de Vírus de Planta

Many methods can be used for arriving in a correct virus disease diagnose, and the serological techniques are the most used methods for plant virus identification. The indirect enzyme-linked immunosorbent assay (Indirect-ELISA) or plate-trapped antigen ELISA (PTA-ELISA) has been useful for detection of viruses in a wide range of situations, especially to test a large number of samples in a relatively short period of time. Immune-biological Companies have developed practical kits for direct ELISA or double antibody sandwich (DAS-ELISA), but neither Company has developed kits for PTA-ELISA. As a single universal antibody-conjugate is used for detection of a wide range of plant viruses, the PTA-ELISA technique is more economical, practical and suitable for virus detection. Considering also the great problem of including infectious plant viruses in DAS-ELISA kits, a simple kit for PTA-ELISA was developed for plant virus identification. Extracts from infected plant tissues were added into the ELISA plate wells, which were sealed with plastics and maintained in the refrigerator and Laboratory conditions for different periods of time. The plates were tested by the regular PTA-ELISA and after 20 months of incubation, the plate showed excellent results when used for detection of six virus species from the genera Comovirus, Cucumovirus, Potyvirus and Sobemovirus in infected plant tissues. The ELISA plate trapped virus together with its specific antiserum could constitute a simple kit, which will permit the exchange of antisera among virologists without transferring infectious viruses from one laboratory to another to be used as control.
A Two-Stage Failover Mechanism for High Availability in Service Function Chaining

Service function chaining (SFC) enables specific network flows to be processed through an ordered set of service functions. In this paper, we propose a two-stage failover mechanism to provide high availability (HA) in SFC. In the proposed mechanism, a secondary service function path (SFP) is pre-computed, which is maximally disjointed with the primary SFP, and a backup service function instance (SFI) is prepared for each service function. For a failure event, the first local repair stage is examined by means of the preconfigured backup SFI. If the backup SFI is not available and/or any link is failed, the second end-to-end repair stage is triggered by replacing the primary SFP with the secondary SFP. Simulation results demonstrate that the proposed failover mechanism can reduce the recovery time by 50%-75% compared to the conventional approach.
BUYER-SUPPLIER RELATIONSHIP AND ORGANIZATIONAL PROFILE : SOURCES OF PRODUCT INNOVATION IN INDIA AND PAKISTAN

The linkage among supply chain innovation focus, buyer-supplier relationship and product innovation requires better understanding in general and in the context of emerging economies of Indian Subcontinent particularly. This paper tests a theoretical model arguing for a positive impact of supply chain innovation focus on buyer-supplier relationship, which in turn impacts product innovation and business performance positively. Also, the paper seeks to explore association between organizational profile and product innovation. The empirical study of 296 organizations from India and Pakistan using structural equation modeling and hierarchical regression provides insights as to how buyer-supplier relationship and organizational profile impact product innovation. The paper concludes the findings and proposes future research directions.
Effect of low temperature on seedling characters and yield of boro rice (Oryza sativa L.).

Low temperature during December and January is major constrain for boro rice cultivation in northern part of West Bengal. Very low temperature (10 ± 5 C) and low light-intensity during those months inhibit normal growth leading to stunted growth and degradation of chlorophyll. The leaves turned yellow and became albino at extreme low temperatures (<10 C). After mid-February, temperature rises gradually and the seedlings also get full sunshine due to clear sky and the seedlings turn green in colour. In the present endeavour, 37 genotypes of rice were screened against low temperature at nursery for seedling characters (seedling height, shoot fresh weight, shoot dry weight), scoring for leaf bleaching, days to 50% flowering and yield under agro-climatic conditions of northern parts of West Bengal. The genotypes Parijat, Krishna Hamsha, IR 64, UBKVR-5, UBKVR-6, UBKVR-8, UBKVR-16, UBKVR-17, UBKVR-19, UBKVR-21, IVT-B4001, IVT-B4007, and IVT-B4008 were found to be low temperature tolerant at seedling stage based on leaf bleaching scoring (1-9 scale). Crop duration was more (varied from 20 to 35 days) for the genotypes grown in Boro-season than in Kharif. There was no notable difference in yield of the genotypes for the different dates of sowing in Boro-season.
Determinants of citation impact in the Global South

In this article, we applied bibliometric and econometric analysis to identify which countries are producing research with higher scientific influence, and to understand which factors lead to those higher results. We focus specifically in the Global South because some of these countries are starting to converge in terms of output with the Global North and we found some evidence suggesting that at different levels of wealth intensity countries have different determinants of citation impact. However, our econometric analysis suggests that most of the same factors hold for both groups of countries. We found that previous citation impact, level of international collaboration and publication output in a specific scientific field are important determinants of citation impact in the Global South, as they are in the Global North. Industry collaboration and having English as an official language seem also relevant to some extent. We propose possible explanations for the patterns found and derive some policy implications.

Creative Construction Conference 2018 , CCC 2018 , 30 June-3 July 2018 , Ljubljana , Slovenia An Integrated Multi-Attribute-Decision Making Approach for Selecting Structural System : A Case Study

A structural system is the essential component of a building, which carries all loads acting on the building and transfers them effectively to the soil through the foundation. The design team, which includes engineers and architects, is in charge of determining the most appropriate structural system that will fulfill the owner’s and end user’s requirements as well as the legal requirements. Selecting the most appropriate structural system is a difficult task as there are many factors that need to be taken into consideration. Therefore, this problem can be considered as a multi-attribute-decision-making (MADM) process. This study proposes an integrated MADM approach for solving this problem, which uses the analytic hierarchy process (AHP) and Vise Kriterijumska Optimizacija I Kompromisno Resenje (VIKOR) methods. In the proposed approach, AHP is used to find the weights of the criteria and VIKOR is used to rank the alternatives. The proposed approach was employed in a real case. Extensive review of the relevant literature was carried out and the face to face interviews were conducted with four engineers of the design team, which was responsible for the selection process of structural system in the studied case, in order to identify the criteria that may affect the selection of a structural system from the managerial perspective. A total of 5 main criteria, namely the durability and safety of the project, the energy consumption, the project characteristics, the total cost, and the constructability problems, and 19 corresponding sub-criteria were identified. The findings of this study revealed that the proposed approach can be a useful tool in selecting a structural system. © 2018 The Authors.

A document analysis of the visibility of sustainability in TVEteacher education programme: the case of a Malaysian HEI

There has been a global call for institutions of learning to engage in Education for Sustainable Development (ESD) by leading world organisations. Although scholars advocate for an interdisciplinary approach to sustainability, the research literature shows that majority of sustainability issues are addressed through fields such as environmental and developmental education. There has also been a call for the integration of Sustainable Development (SD) in Technical and Vocational Education and Training (TVET) programmes by various scholars and bodies such as the United Nations Education, Scientific and Cultural Organisation (UNESCO). The issue, however, is that Technical and Vocational Education (TVE) programmes are not yet embracing this call to integrate ESD into their programmes. Hence, it is imperative to reiterate the intersection between TVE and SD and how the former can contribute significantly to the SD agenda. Therefore, by completing a qualitative documentary analysis of a TVE programme, using a Malaysian Higher Education Institution (HEI) as a case study, this paper discusses the visibility of sustainability in TVE programmes as well as explores the overarching goal of ESD and why it is especially crucial for TVE. Findings reveal that the concept of sustainability is only barely reflected in the TVE teacher training curriculum. Recommendations for practice change and further research are presented and discussed.
Life Span Cognitive Development of Age Groups and Its Influence on the Determinants of Early Stage and Serial Entrepreneurship

Earlier studies in entrepreneurship identified an inverse U shape relationship between age and entrepreneurship (Parkar, 2004; Hart et al., 2004). But to date it is not certain why such kinds of relationship exist. One of the reasons may be the cognitive development of age groups which influence the determinants of entrepreneurship. This study has been initiated to investigate how life span cognitive characteristics of age groups modify the influence of opportunity identification and start-up skills in early stage entrepreneurial activity and in serial entrepreneurship. To answer these two questions we developed two series of logit models for interaction terms to test our hypotheses. We used margin analysis and double difference technique to identify interaction effects in our analysis. The study identified that opportunity identification has more positive influence on early stage entrepreneurial activity when the opportunity is identified by young adults rather than the other two age groups. On the other hand, opportunity identification has more influence on serial entrepreneurship when the opportunity is identified by older people rather than the two other age groups. There is no significant difference between young adult and middle age people in the influence of opportunity identification in early stage entrepreneurship when we compare only these two age groups. However, this difference is significant in serial entrepreneurship. The result is almost similar in case of age effects on skills in both early stage and serial entrepreneurship.
